Hi Robert.

Please try doing this:

1. Please download the fsx_path_fix.zip file.
2. Unzip it to FSX Root Folder - please make sure this is the folder of FSX you are currently using.
3. Double click it to run. If you use antivirus software please allow to run the file. Please make sure you have Administrator rights at your computer. Wait for some seconds.
- If you placed the file into wrong folder you will get the message: '...Please make sure you run this file from your FSX root folder. Currently the file is located in wrong folder.'
- If you placed the file into correct FSX root folder you will get the message "The operation completed successfully. Press any key to continue'.

I took this from  KB# 3521 (CS WxR solution). I believe that following these instructions might fix the problem you are having with Weapon for FSX because it still thinks that FSX is in the default location.

I hope this helps.

Mark
