2) click on this entry, now look in the right side vane for the 'UpperFilters key'. For FSX and their validating system, it should only read, 'PartMgr'. In your case, there is a chance it shows something more. In my case, it was reading: ShockprfPartMgr, or maybe in your case, just '0' 3) double click on the 'upperfilters' key and make a note of what the exact wording is, as you may have to put it back later, now in the opened box, change the registry key to read only ' PartMgr' ( no need for the commas ). Click OK and exit. You may have to reboot.

Fsx Acceleration Expansion Pack Serial Numbers. Convert Fsx Acceleration Expansion Pack trail version to full software. Having uninstalled and reinstalled the acceleration pack one two many times when the product key is entered you can not activate it via internet says by phone or activate later. Cannot activate by phone get error message product code not found. Bullit activate later game starts. Called Microsoft support and. Linkoptimizer Serial.

4) start FSX, you may now be prompted again with the activation dialog, proceed as beforehand and let FSX start, ie, start a default flight at least, then exit FSX. I am not sure I can help here, but just to make things clearer than your first post, 1)Did you activate twice? Once by phone and once by internet? 2)Could it be that it is not FSX that needs to be activated, but your add on aircraft? Some of them will only allowed installing once,mon one system.

Thereafter you might have to ask for help from the add on publisher to unregister the old install and reregister the new one. Do you also have this problem with default FSX B737? If not, than it is an add on problem.
