I already responded to another topic, but few people willl be patient enough to go to page 3...
For everybody having the following problem
Error (2732) as installing 4.6.4.
Or .\Boostrapper.cpp:886 0x643 Fatal error during installation.
I could not even uninstall !
Here is the Ultimate Fix
-Go to 'C:\Users\USERNAME\AppData\Local\Temp\Evernote.msi' and execute it
Here are other things I tried, but I'm not sure about the results.
Here is alternate fix, I reversed the Evernote msi, seen the logs and fixed what's going on.
Fix 1 (Try ultimate Fix above first)
-Go to folder : C:\Program Files (x86)\Evernote\Evernote
-Execute the following command line in admin mode : regsvr32.exe /u EvernoteOL.dll
Fix 2 (Try ultimate Fix above first)
-Go to C:\Users\USERNAME\AppData\Local\Evernote\Evernote\AutoUpdate
-Execute the last version. (it will probably fail again)
-Rexecute the following command line in admin mode, just to be sure : regsvr32.exe /u EvernoteOL.dll
-Install only for this user C:\Users\USERNAME\AppData\Local\Temp\Evernote.msi
For the Evernote team
Your problem comes from the Unregisterx64OLAddin action.... I have no reason why.
regsvr32.exe /s /u "[APPLICATIONFOLDER]EvernoteOL.dll"
I am not sure why... but my logs show than when I execute .msi directly, then it execute Unregisterx64OLAddinNotAdmin instead, it worked. (my UAC in disabled)
When executing en .exe, the Unregisterx64OLAddin was running and crashed. So I'm not able to tell you if the fix was me running the command regsvr manually OR running .msi directly.
I guess than running MSI manually worked with because I selected "Only this user" made the condition : Installed AND (OUTLOOK_BITNESS ~= "x64") AND ALLUSERS AND AdminUser AND (NOT ((VersionNT = 501) AND (VersionNT64))) false so Unregisterx64OLAddinNotAdmin runs instead.
