February 22, 20179 yr My update to 1607 went smoothly yesterday...deferred for quite a while...has to reinstall DisplayLink driver as expected, Started testing various apps. Found out that the update deactivated FSX which was running fine on 1511. Tried a repair from the DVD but it fails every time with an InstallShield error. Tried an uninstall ...was able to uninstall Accel pack but FSX will not uninstall with a Fail to load a DLL for uninstall. Tried to reinstall Accel but it see FSX is deactivated and will not proceed. Anyone seen this issue...any fixes? I tried everything I could find on the Internet but nothing has worked.
February 22, 20179 yr Tried to contact Microsoft? They give distance-support on the Windows 10 updates.
February 22, 20179 yr Author Talked to them this morning no resolution yet...or answer to why 1607 de-activated FSX
February 22, 20179 yr Can you run a restore point? Can you right click on the FSX install and run as administrator?
February 23, 20179 yr Author Update 1607 deleted all previous restore points but resolved this evening. Had to manually search and delete any entry in the registry for Microsoft Flight Simulator related specifically to fsx.exe. This allowed he Remove to execute with the DVD...reinstalled FSX and activated. Installed Accel Pack and launched FSX and the validation error was back. Went into the registry and found 4D36E967-E325-11CE-BFC1-08002BE10318 (key for FSX) and edited the UpperFilters setting...deleted the prtmgr value and retyped PartMgr and saved. Launched FSX and the activation window for Accel pack appeared immediately. Activated with the product key and away it went. This was a 24 hour pain...but all is back to normal after the 1607 update.
