on a firefox install i get the message "Error! Cannot initialize plug-ins directory"
I have tried multiple times to download and install the latest Firefox and I always get the error message above. This doesn't happen on other software installs. My OS is Windows 7 Enterprise, SP1.

Remove Firefox's plugin registry file Sometimes the pluginreg.dat file becomes corrupted. You can remove it and have Firefox re-scan for plugins. As a side effect, any plugins you have disabled on the Add-ons page probably will be re-enabled, so you'll need to go back to that page one more time.
Close Firefox. Open your file browser to this hidden location:
- Mac: *~/Library/Application Support/Firefox/Profiles
- Linux: *~/.mozilla/firefox/Profiles
- Windows: %AppData%\Mozilla\Firefox\Profiles
- *C:\Users\<user>\AppData\Roaming\Mozilla\Firefox\Profiles
Search for the above file. Then rename or delete them. Restart Firefox.
