I apparentley did not have FS9.1 installed. and therefore nothing have changed.
I found the following on Internet.
Update Error Type: 34
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
You may receive the "Update Error Type: 34" error message if there is a registry value that is not valid for the location of the Fs9.exe file. To resolve this error message, correct the EXE Path string value in the registry. To do this, follow these steps:
1. Click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and then select the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Games\Flight Simulator\9.0
3. Right-click the EXE Path string value, and then click Modify.
4. In the Value data box, use one of the following procedures, and then click OK:
* Type the correct path of the Fs9.exe file. For example, type C:\Program Files\Microsoft Games\Flight Simulator 9 in the Value data box.
* Delete the path in the Value data box.
5. On the File menu, click Exit to quit Registry Editor.
6. Double-click the Fs91upd.exe file to install the update.
Behind Flight simulator was a \ which I removed as suggested on the Internet Forum.
The update stated to installed until lit stopped at Processing modules\ABLSCPT.DLL.
Do you know what this is, I then cancelled. the update.
The last line in 4. *Delete the path in the Value data box, I presume it does not mean the path I had just altered.
In my Fl.Sim 9 map is next to the fs9 the FS9.1 update file. Is this correct
