VSTO add-ins not loading

We are in the process of moving from 2010 to 2013. There have been a couple VSTO add-ins for Office that used to work fine with 2010 but no longer work in 2013. Trying to enable them through the Add-ins menu does not work, and it says "Not loaded. A
runtime error occurred during the loading of the COM add-in."

Hi,
This issue may be caused by the development environment changed, please see the below articles to troubleshoot this issue.
Troubleshooting COM Add-In load failures
My Office Addin does not Load!
If you want to do further troubleshooting, such as debug code, I recommend you post the question to VSTO forum:

The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who read the forums regularly can either share their knowledge or learn from your interaction with us. Thank you for your understanding.

Analyzer 7.0: Excel add-ins not loaded on opening workbook

Hi all,
we are having a problem with some of our workbooks which are using additional functions from a standard microsoft add-in (Analysis Toolpak - function "mduration" for exmaple).
The add-in is checked as "load" under Extras->Add-Ins.
Opening the workbook without analyzer is just fine.
When opening BEx Analyzer 7.0 and then the Excel workbook, all functions from the add-in (such as "mduration") only return #NAME, as if the add-in is not loaded properly.
Using BEx Analyzer 3.5 this DOES work, however.
We are on SAP GUI 7.10 PL11 with BI 7.0 Add-On SP10. Excel version is 2003.
Does anyone kow whether this is a known problem or if a solution exists (maybe with latest BI Add-On SP)?
Thanks,
Hendrik

XLReporter Com Add-in not loading

I have a problem with the XLReporter and am having a problem getting pointed in the right direction. Here is what is going on. We have the B1 client installed on our Terminal server to make it easy to demo. When someone needs to demo B1 from outside the office they use an RDP connection to the Terminal server and start the B1 client. They go to run the XLReporter, generate a report and get the error Com Add-in not loaded. But, when you open Excel and go to the Com Add-in it shows that it is loaded. This was the result even with the administrator logged in. When I log in to this server with my log in I have no problems, the reporter works good. I have been through a complete uninstall and reinstall of the client. I even removed all left over files from the first install to include running the IXXL registery cleaner tool. I did the reinstall under the administrator login. I hope that you can get me pointed to the right place for info on this. The system is B12007A-47 on a Windows 2003 server with SQL2005.
Thank you for your time on this matter.
John

Gordon, I have opened Excel and manually added the IXXLReporter.dll to the Com Add-in while I was logged in as Administrator.It will not start.
Jim, the 2007A B1 client that is installed on the computer auto installs the XLReporter when you install the client. I have uninstalled the client, ran the registry cleaner for XLR and then reinstalled. I did all of this while logged on as the administrator. Still wont work while logged in as administrator. But, when I log on as myself it works

Adobe Acrobat v8.1.2 - PDFMaker COM Add-in not loading in Word 2007

PDFMaker COM Add-in is now not loading in Word 2007 at startup. But, it loads just fine for the rest of the Office 2007 apps. It loaded just fine, all operational, until 1-2 months ago. Now I have no access to Acrobat in Word 2007 except for print to that printer. There are now no buttons on the ribbon for direct access to Adobe Acrobat functions as there used to be. When I look in the COM add-ins area of Word 2007, it tells me PDF Maker is not loaded and that I cannot change the connected state of Office Add-ins registered in HKEY_LOCAL_MACHINE in the Regedit.
Am running MS Office 2007 SP-1 on Vista SP-1 x82. This behavior was going on before the recent SP-1's were installed, so pre-existing condition. Everything else is performing quite well. REALLY! I am very pleased with Vista.
Guidance, help, etc is most appreciated. THANKS!!!

I had the same issue. The COM Add-In for PDFMaker was disabled by Word 2007 due to an unexpected crash during the creation of a PDF. I have searched all over the place trying to find a way to get the PDFMaker functionality active again in Word 2007 including the solutions mentioned in this post. In the end I found a solution myself.
1. Go to Word Options > Add-ins
2. Go to the Manage drop down dialog at the bottom of the page and select Disabled Items. Click Go.
3. A dialog will open that displays all the disabled add-ins. Select Acrobat PDFMaker Office COM Addin.
4. Click the Enable button.
5. Close and reopen MS Word and the Acrobat menu should be available again.

Icloud-Outlook-Add-in not loaded automatically

Dear Support Community,
I've been using my Iphones together with my Win PC / Outlook for several months.
No problems.
Since a few days, there's always the problem, that the "i-cloud-Outlook-Add-in" is not
loaded automatically, when I start Outlook.
Manual activiation (via Options -> Add-In --> Com Add-in --> tick in the box at "i-Cloud ...")
works perfect.
I've checked the registry entry "LoadBehaviour": 3 --> correct value, in my opinion.
Any ideas, how to get outlook to load the icloud add-in automatically at startup?
Thank you very much in advance.
Regards

I just had a user call in with this exact same problem. The steps that I took to resolve the issue are as follows:
1. Ran a repair on office installation and rebooted computer. (Not sure if this was nesary).
2. In Outlook go to File-Options-Add-Ins. Below for Manage COM Add-ins click the Go button.
3. find iCloud add-in and check it off to enable it. Click on OK until your back at outlook.
4. Close and relaunch outlook. Go back to File-Options-Add-Ins and down at the Manage change the dropdown to "Disabled Items".
5. Choose the iCloud.dll checkbox and click on enable.
6. Close outlook and reopen. You should now see the ribbon for iCloud sync.

Adobe Acrobat Pro X - plug-ins not loaded

I recently purchased Adobe Acrobat Pro for our company with multiple user licences. Once installed I noticed a lot of features which were in previous versions are not available. When I select the “Help” “About Adobe Plug-ins...” tab, almost all of the plug-ins are not loaded. Is this right and if not, how do I fix it. After reading numerous blogs I still do not have an answer – most refer to 3rd party plug-ins but not to this problem. NB: I am not an IT expert, but can help myself fairly well on software. Using Windows 7. Uninstalled Google Chrome as someone suggested it affects the plug-ins (which also did not solve the problem!)

It's working correctly.
The Help > About Adobe Plug-ins dialog shows the status of dynamic extensions which ship with Acrobat - not third-party plugins you may have installed yourself. These core extensions are loaded on demand, so if you don't have a document open, very few of them will be loaded. It's why the dialog bothers to tell you their status in the first place.
Third-party plugins need to be reinstalled if you upgrade to Acrobat X, as the installation folder is different. Some that were written for previous versions won't work with Acrobat X, especially if they're not designed to cope with the Tools Pane or Protected View in 10.1, but they will not appear on that dialog - they appear on the next menu item down, "About Third-Party Plug-ins".
The UI in Acrobat X is radically different from previous versions, but very few features are actually missing - what are you looking for that you can't find?

CS6 InDesign plug-ins not loading when launching

I just purchased CS6 Standard. when launching InDesign, the adobe plug-ins are not loading causing error messages. I have re-installed twice, but get the same error messages. At the end of several error messages, I get
'Cannot open resourse file." Can anyone help me?

I'm a little confused with what you write. There is a difference between extensions and Plug-ins. Plug-ins are installed using the plug-ins installer and extensions are installed by "Adobe Extension Manager (version)" where version is the Photoshop version and the extension package must be created for that particular Photoshop version. A CS5 package will not work in CS6 etc. Installed extensions will be listed in Photoshop under menu Windows>Extensions>List of them. Plug-in may install in the Filters menu or a place like menu File>Automate>Names. Installed Extensions that you installed should also show in the "Adobe Extension Manager (version)" window. Adobe installed extensions like Kuler and Mini Bridge do not show in the "Adobe Extension Manager (version)" window.

FireFox 3.6.9 Add-ons window not working, add-ons not loading

After upgrade add-ons do not load.
In Add-ons window, no data; all add-ons disappeared;.
Also clicking < Browse all Add-ons > produces nothing, does not link to site.
Navigate toa site to download an add-on: Add-ons window appears but no data or appearance of files or anything. So< Install> button therefore does nothing.

You can delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox [[Profiles|profile folder]] to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled extensions that are not compatible on the next start in "Tools > Add-ons > Extensions" then click the "Find Updates" button to do a compatibility check.

Certain add ons/plug ins not loading. For example, in eBay, mouse over certain items and only blank dialog box pops up, no text within box. What could be causing this?

Appears to be flash or Acrobat issue???

Probably caused by the Google Toolbar extension. Disable it to verify it as the cause.

VST plug-ins not loaded at all Snow Leopard 10.6

Hi
I am using abelton live, and install waves 7 (does support snow leopard 10.6), and I don't see any recognition whatsoever for VST in premiere cs5
if I go inside the package of the application , i can see the plug-ins folder, but where is the "user" plug-ins folder.
on a Mac the folder is in /Library/Audio/Plug-Ins/VST
this is not the location where premiere is looking to load the VST, in the splash screen you don't see it loading Waves plug-ins for example.
does anyone know why / how to truely enable VST on CS5 Mac?
thanks
Ami

Arri,
Usually, PrPro will survey most of the system, and load all VST's found. However, three things can happen:
1.) the VST is loaded and can be used by PrPro (not sure if this is the case with your particular VST)
2.) the VST is loaded, but PrPro cannot use it. There is most often a one-time message to this effect. The VST will NOT appear anywhere in PrPro.
3.) PrPro attempts to load the VST, but cannot. At this point, in later versions, a blacklist file is written, and each such VST will be added, when one launches. The launch will fail, until all such VST's are "blacklisted." When that blacklist has been completed, PrPro will launch fine, ignoring each of those problem VST's.
Just not sure about your particular VST. Does it say that it will work in PrPro? Not all will.
Good luck,
Hunt
PS - seems that there are a couple of threads on Wave7.dll, but do not recall the specifics. I'd suggest a Search of this, and maybe the CS4 and Earlier fora, and some reading.

Adobe Plug-Ins not loading

Hello,
I'm having a problem with my computers loading all of the default Adobe Plug-Ins such as "Comments". I've used Adobe customization wizard 8.0 to package Adobe Acrobat Standard 8.1.2 and deploy it through Windows 2003 Group Policy. All of the computers have a previous version of Adobe Acrobat Standard 8.0 loaded on them. I've ran "Repair Acrobat Installation" and validated that the api files are in the plugin directory. The only domain change made was a group policy adm template file was created to disable "Java Script" in the Acrobat program because of malware. This applies to the users when they login and is located at "HKEY_Current_USER Software\Adobe\Adobe Acrobat\8.0\JSPrefs". The weird thing is I've been able to deploy this package to some of my test machines and virtual machines and everything installs fine. The test machines are located in the same containers has my production machines. Any idea what could be causing this problem?
Any help would be greatly appreciated!

Sorry, I reported this wrong. I updated the package from 8.2 to 8.2.1 and then redeployed it. Do you think I should try rebuilding the packages starting from the first update to the last?

Plug ins not loading

I reinstalled elements 11 to a new drive and dragged the entire old plug ins folder to the new drive plugins folder, but no plugins are showing up in the editor.

Well, you probably made a mess. Many third-party plug-ins use external libraries and need to be installed properly just like the main program. In any case, we cannot know. You are not providing enough information.

Plug-ins not loaded?

Hi,
I'm a CC 2014 user on my Mac. But, we have a PC here in our department that has an old copy of CS4 InDesign on it. It doesn't really need anything newer than that, for the work that's done with it.
This PC just got a new hard drive. The old one crashed. So, actually, this new one is a solid state drive. So, it's nice and fast.
I've installed InDesign CS4 now twice. Whenever we open an ID document or template, we get a message saying that it can't open the file because plug-ins are missing. What can I do here?
Thanks.

You’re trying to open files created in a later version of InDesgin.

Space Designer Plug-ins Not Loading

Hi, whenever I try to select a Space Designer plug-in with Logic Pro 8, I get a pop up which says 'no audio file selected' and asks me to 'please locate the file'. I've checked the Logic folder within the Application Support folder of the Library, and all the .pst files are there in the Plug-In Settings folder, but when I navigate to them from the pop up they are greyed out, making it impossible to select them manually anyway. All the other Plug-Ins (Compressor, Reverb, etc) seem to work fine. The problem only appears to exist with Space Designer.
Any help would be greatly appreciated.
Many thanks
Phil

Hi, and thanks for the reply. I couldn't find the Impulse Response folder you mentioned, but just for information, the pop up prompts me to locate the file (for example) '01.4s Jazz Vocal Room.SDIR', and in the bottom pane of the pop up it says 'No Audio FIle Selected', probably because I haven't located and selected the file it's looking for.
Thanks again
Phil

Office 2007 add-ins will not load on Windows 7 x64

Hi there,
I have a brand new built Windows 7 x64 desktop with Office 2007 32 bit installed. When I install Oracle BI Publisher Desktop 11.1.1.7.0 it loads without errors. Except none of the add-ins will load. I have done the usual Add-ins / Com Add-in / Tick box but nothing.
After further investigation it appears there is a VSTO 4.0 error on the machine when I run the C:\Program Files (x86)\Oracle\BI Publisher\BI Publisher Desktop\DotNet2007\TBAddin.vsto. The error itself is only failed when it tries to download savexmldata.png from C:/Program Files (x86)/Oracle/BI Publisher/BI Publisher Desktop/DotNet2007/Resources. The fact is there isn't a folder called Resources nor a file called savexmldata.png.
I thought it may be an assemblies error and tried installing the newest versions of Microsoft Office 2007 Primary Interop Assemblies and Microsoft Visual Studio 2010 Tools Office Runtime (x64) but all are up to date.
See below for the error:-
