What this does is destroy all Adobe Software and After-market Plug-ins by completely removing them and clearing the system registry. Into week 6 now with this problem and still no fix. Last Phone into Adobe Support had me remove Several folders from system and destroyed all Adobe software and plug-ins. Folders were: C:/Programs/Adobe, C:/Programs86x/Adobe. C:/ ProgramData/Adobe. After which Adobe CCleaner was run and system rebooted. This removed all Adobe products from System. On reinstalling only CC and CC2014 products were reinstalled, CS5.5 and CS6 products were lost and all After-market Plug-ins, some of which were mode locked and they cannot be reinstalled. The kicker is Adobe Extension Manager Failed to update and still returns error code u44m1p34.
The AdobeExtensionManagerCCall.zip file did contain Media_db file, but this install failed as well and returned same error code.
I have made 9 phone calls to Adobe Support, 9 chats sessions and several e-mails. All of which ended in complete failure to fix problem error. A little over 19 bad guesses by Adobe Support Staff. I have 6 weeks of failure by Adobe Support Staff. Who up to this point have only been making bad guesses as to how to get Adobe Extension Manager CC to update and clear Error Code u44m1p34.
The solution you offered failed to clear the error code or update the program.
