Here is a picture of the file I want to open, and the program I want to open it with:
If I just click the jar file, it opens my program smoothly (I made that Java program myself), no questions asked.
If I click the file and choose the program in the picture as my default program, it says this:
If I do all this with .txt as the file extension it says the same and still doesn't work.
If I do all this in Windows 7 with the same setup, it all works fine.
I also checked my event logs when this occurs and this pops up as a keyword "Audit Success" with the text:
An attempt was made to query the existence of a blank password for an account.
Do you have any idea what might cause this?
