App disappear after update

i have same issue when user download updates then my program open then disappear and this is happen with some users not all users

i have automatic update dll to my projectwhen i removed it and use wyupdate.exe its running well

Like I said in the other post you made:

Details are need:

1. Versions (version of wyBuild, version fo wyUpdate, are you using a custom version? Or our pre-built version?)

2. Code

3. How you're using it, etc.)

9 times out of 10 it's because your code is not following our examples.

Hint: never use the ForceCheckForUpdate() function.
