I'm getting this error 'Unexpected installation error -203 when installing add-ons'

this occurs when I try to update existing extensions or install new ones. I have followed the information in this article [https://support.mozilla.com/en-US/kb/Unexpected%20installation%20error%20-203%20when%20installing%20add-ons] but neither solution helps. Windows firewall has firefox listed as an exception, and i tried deleting the files suggested
o extensions.ini
o extensions.cache
o extensions.rdf
the problem is still there... any ideas?

They are also for the Mac. If the first link that cor-el posted is showing information for Windows, in the right hand column underneath where it says "Help with", select Mac OS X and Firefox 3.5-3.6

"Error opening installation log file" when installing Photoshop Elements 10

I bought Photoshop Elements 10 , Premiere Elements 10 .... I got the Premiere to download no problem but i can't get the photoshop to download. This is the msg that I am getting when I try to dl it "Error opening installation log file. Verify that the specified log file location exsists and is writable". Not sure why I can download one and not the other since they are both on the same disc. Plus in the program that I purchased I has 5 DVD's. Any suggestions??
Thanks

Dear Vinoth,
Similar problem was faced by me also.I uninstall the whole SAP Setup .After that Delete SAP folder from Program files where u installed it.
Also in START->RUN->%temp%
Rename the folder "SM_OBS_DLL" to any name you want.
Then install SBO setup and then addon.
Try this it will work.

Hi,
It’s version 13.1.1 It’s a trial version.
I am updating it from the Creative cloud desktop application.
I have the photography subscription with Lightroom and Photoshop with Creative Cloud.
I was interested in trying out the video software and have trials of Premiere Pro as well as others. The CC desktop app alerted me to the AF update just as it does for the others I subscribe to plus the ones I am using as trials. I have not had any problems with the other apps (trial or not), only with AF.
Thanks.

After installing Trend Macro antivirus, I was unable to install any plugins. I get an "Unexpected Installation Error" message at the end of the installation. Closing the anti-virus does not help.

I have purchased Trend Micro Titanium Maximum Security and am now unable to install any plugins. I have had these plugins before and had no trouble with them but now they have disappeared. I tried closing the antivirus and added mozilla.org to the exceptions list but it did not help.
I have copied the text of the error.

The device has encountered an unexpected error. Installation error: application verification failed

the device has encountered an unexpected error. Installation error: application verification failed
I have been receiving this message over and over again when trying to publish my iOS app for the app store (I use Flash cc AIR 3.9.1.1080 for iOS and my settings are: "device testing in interpreter mode", as my app uses several swfs).
I have done everything from scratch, as recommended on other sections of the forums: new app ID from my apple developer account, new Distribution Certificates, new Distribution Provisioning Profiles and nothing works.
I can install my app on my iPad if I use the development Certificate and Provisioning Profile and everything seems OK. But as soon as I use the Distribution Certificate and Provisioning Profile get the same message:
the device has encountered an unexpected error. Installation error: application verification failed
I have done everything from the beggining over and over and nothing works. Am I the only one having this issue on Flash cc???

Hi Daniel:
I´m far from being an expert on Xcode (or any code) but this is what I did and it worked:
- On Xcode go to Preferences > Accounts > select your App Developer Account, then click "view details" on the lower right corner.
- There you can see which of your "Signing Identities" (Certificates) are "Valid". You should have at least one for Development and one for Distribution.
- Below that window there are two icons which you can use to add, export or revoke a "Signing Identitie" (Certificate).
- Choose the one you want to use (Develop. or Distrib.), export it to the folder of the app you are working on and name it in such a way you can relate it to your app. Before knowing this I was exporting them using Keychain Access and I wasn´t naming them to differentiate each one properly.
- On your Apple Developer account create the Provisioning Profile for your app. I deleted any App IDs or Prov. Profs. which were useless.
- Then on my Apple Developer account I generated a Development Prov. Prof. to install and test my app on my iPad. All went fine.
- Then an Ad Hoc Prov. Prof. again to install and test my app on my iPad. All went fine.
- Then I generated the App Store Prov. Prof. and I was able to install the app on my device without the upsetting error.
- Then I uploaded the app to iTunes Connect with no problem.
These link was useful for me: https://developer.apple.com/library/ios/technotes/tn2318/_index.html#//apple_ref/doc/uid/D TS40013777-CH1-TNTAG0
You can also search for "Certificates" and "Provisioning" on Xcode help.
Good luck!
