Cannot Open .xls files in Excel 2010
Before we start, I would just like to say, I've read probably 9 or 10 other threads with no help.
I cannot open any .xls file. Unfortunately the user has already associated the file type with Adobe Reader, so I cannot just double click the files to open them. I have tried the follow fixes with no solution:
-Open With .. > EXCEL.exe (I double click the application and nothing happens)
-Going in to the file extensions page and associating it with the EXCEL.exe application there, but same thing, nothing happens
-I have tried going into the registry and renaming the "OFFICE12"'s to "OFFICE14". Nothing happened
-I have tried going into the Excel folder options and checking off and unchecking "Ignore Other Applications That Use DDE"
-I have searched for the "Microsoft Application Virtualization DDE Launcher" application with no luck
of finding it
-I have tried re-installing and repairing Office 2010
I'm out of idea and have no idea what to try next. Any ideas?
Hi,
The registry key which could affect you open the .xls by double click is the following:
Important
This method is related to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you do it carefully. For added protection, back up the registry before you modify it. Then, you can restore
the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
322756 (http://support.microsoft.com/kb/322756) How to back up and restore the registry in Windows
HKEY_CLASSES_ROOT\Excel.Sheet.8
I would suggest you rename the registry key, and then repair the Office programs to create a new key.
For example:
Rename “Excel.sheet.8” to “Excel.sheet.8.old”.
Then repair the Office programs:
Start > Control Panel > Programs and Features > click the Office 2010 program that you want to repair, then click Change > Repair > Continue.
You might need to restart your computer after the repair is complete.
Sincerely

Cannot open project file in Project 2010
Hi,
I have a project created in Project 2010. I can save it without any problems. But some saves are broken and I cannot open them again. When I open saved project an error message is displayed:
There was a problem sending the command to the program and Project freezes. Project 2010 itself starts without any problems. What's strange I can open this file in viewers like MOOS Project Viewer 2.0 but not in Project.
Any tips highly
appreciated.
Lukasz ChominHi Lukasz,
Welcome to this Microsoft Project newsgroup :-)
It sound as though that project has corruption. If you can open it at all, follow the advice given below. If you can’t open it at all, it seems like it’s lost – you do have a backup don’t you?
If you can open it in another program, try copy/paste the data back into a new project.
If you suspect a corrupt file, you could try the suggestions in FAQ Item: 43. Handling project file corruption and/or bloat.
FAQs, companion products and other useful Project information can be seen at this web address:

Hope this helps - please let us know how you get on :-)

Cannot open .wav files from Outlook 2010 (beta)
This file the error message i get:
This file cannot be previewed because of an error with the following previewer:
windows media player rich preview handler.....Hi,
First, try to start Outlook in safe mode to see if it works fine.
If it works fine in safe mode, disable the add-ins you have in File > Options > Add-ins.
Second, try to clear out the Outlook Temporary items.
1. Locate the Outlook Temporary Items folder by opening the Registry and
locating
HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\Security\OutlookSecureTempFolder
2. Navigate to the value of this Key. It should be something like:
%USERPROFILE%\Local\Microsoft\Windows\Temporary Internet Files\Content.Outlook\
3. Quit Outlook
4. Delete the contents of the folder
5. Launch Outlook
Hope it helps.
Had this same problem. End of key was like "CK2219B0\". Deleted this small portion, saved registry, and restarted Outlook. .wav files executing fine now! Musta been some kind of update glitch cause it worked up to a day or
so back and then I had this problem. Thanks!!! -
Hyperlink - Cannot open specified file in excel
I have created an excel document with hyperlinks to other documents on our drive. For some reason when I click on the links i get the above message. But the file pathway that is correct.
I have over 200 link and do not want to enter them in again manually.
PLease helpHi,
Which version of Excel are you using?
Have you changed the file path where the linked documents are saved?
If we manually modify a problematic link, will it work correctly then?
Please also check the following setting of your Excel. Click File > Options > Advanced, scroll to the General section, then, click the Web Options button. Make sure the check box before "Update links on save" is not checked under Files
tab.
In addition, we may consider to use VBA code to refresh/update your hyperlinks to see if it will make any difference. Since we are not the best resource for coding, you can post coding related question in the following forum:

After file encryption in Windows 7, Excel cannot open .xlsx file
I just moved all my files to a new laptop with Windows 7. I was using Excel 2007 and Windows XP on the OLD laptop. The NEW laptop has Windows 7 Ultimate and Excel 2010. I turned on file encryption (via Windows File Explorer) and now I'm
unable to open most Excel files.
The error message says: "Excel cannot open the file 'ABC.xlsx' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file."
I can open the file just fine if I use the backup version from the old laptop. It appears that the Windows 7 file encryption damaged the file from Excel's perspective. No other applications are showing issues and not all .xlsx files are failing.
Any ideas, please?
Thanks,
KenThis is not a solution but a possible work around to see/salvage the contents of your file. If you have a Google Account
Go to Google Docs (https://docs.google.com)
Log in with your credentials
Upload the troublesome files (xlsx, docx etc)
If you are lucky Google may be able to salvage their contents.
Once uploaded, you can always download the file from Google in a variety of formats -
I downloaded mountain lion and then the new office suite (word, ppt, excel) but now when I try to display one of my ppt's it says 'ppt cannot open the file...the file may be corrupt, in use, not a type recognized by ppt etc.." how can I fix it?? HELP
Did you try to open teh fle by double-clicking its icon? If the file was made with an older version of Office, you may get that message. Try opeing PP and, from its "File" menu, see if you can open the ppt. I've foundthat often gets around that message and then yo ucan save the file from the newer version.
If that doesn't work, consider asking in the Microsoft Office: Mac forums here:

I am trying to build a dashboard in 4.5 Professional. When I open the Xcelsius file I get the following message "Excel cannot open the file 'im5.xlsx' because the file format or file extention is not valid. Verify that the file has not been corrupted and that the file extention matches the format of the file"
I went to Task Master killed Excel and then got a new message "the document 'im5.xlsx' caused a serious error the last time it was open. Would you like to continue opening it?" If I say "Yes" the message in the first paragraph re-appears. However, I then cannot find Excel in Task Manager again. I therefore assume Excel is not running but the problem persist, I cannot openthe Dashboard. Any ideas how to solve this problem?
I run XP and Office 2007. I have build many Dashboards on 4.5 and also run Engage 2008.

Can you save the Excel file as 2003 compatible and try again?

I get a message saying that "Excel cannot open the file
Every now and then, when I try opening an Excel file, I get a message saying that "Excel cannot open the file 'file.xlsx' because the file format or the file extension is not valid. Verify that the file has not been corrupted and that the file extension
matches the format of the file.I see this most often when a file has been transferred around a lot and gets corrupted due to bad sectors on hard drives,
bad thumb drives, etc...
Occasionally, I find a repair utility that will....kind of....fix it. You tend to lose all formatting and usually the user
would have to spend more time doing than life than simply starting from scratch. If on a file server, shadow copies
(previous versions) are a god send.
If it happens completely randomly, does it happen more often to the same group of people? Perhaps an update malfunctioned?
Reinstall Office? Try XLSX Open File Tool for recovery your documents (http://www.xlsx.openfiletool.com/)
There could be so many reasons this could happen, but all the above is where I'd start.

Excel cannot open the file beacuse the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file"
After I click yes, the page is blank. The file is about 400kb in size.
I have try open and repair and third party repair program and not working also.

In order to clean your machine, run Microsoft Safety Scanner (http://www.microsoft.com/security/scanner/en-us/default.aspx) to kill the malware, and then repair Excel file itself.
If this is not the case, feel free to post back and let me know. Thanks.

Excel cannot open the file 'file.xlsx' because the file format
Every now and then, when I try opening an Excel file, I get a message saying that "Excel cannot open the file 'file.xlsx' because the file format or the file extension is not valid. Verify that the file has not been corrupted and that the file extension
matches the format of the file.Hi,
Which Excel version are you using? As far as I know, this issue is caused by malware on the affected machine.There are now two known variants of malware which causes this problem: Win32/Crilock.A and
Win32/Buma!rts. They have both been identified as a new family of ransomware.
We'd better clean your machine, run Microsoft Safety Scanner (http://www.microsoft.com/security/scanner/en-us/default.aspx).

Excel cannot open the file because the file format or file extension is not valid
pls help
Hi,
In regarding of the issue, please provide us more information to assist you better.
Which Office version are you using? Office 2013 or other.
Did the issue occur with the special file or every file?
Then, based on your error message, this problem has been confirmed to be caused by malware on the affected machine. There are now two known variants of malware which causes this problem: Win32/Crilock.A and
Win32/Buma!rts. They have both been identified as a new family of ransomware.
In order to clean your machine, run Microsoft Safety Scanner (http://www.microsoft.com/security/scanner/en-us/default.aspx). If infected, Safety Scanner should clean the virus from
the system, however it will not repair corrupted files. You will still need to restore those from a backup. A detailed analysis of affected files submitted to Microsoft for investigation has revealed the files are encrypted with a private
and public key. The files cannot be recovered without the private key, which is more than likely held by the attacker. The premise of ransomware is such that if a person pays the ransom the key is provided to "unlock" the files.
