B4A (12.80) is showing an error at startup, invalid signature.


And on creating a new project or opening any existing project its showing the same and I'm unable to select any library.
Also, its showing XUI not found and Library 'XUI' is not used, both at the same time.

Try to uninstall B4A. Make sure that all files were deleted from the installation folder and install it again.

Finally it worked. The issue was related to a network folder.

So I have my additional library folder and Android SDK on a different computer. So until the previous version, there was no issue accessing the libraries from the network folder.

The latest B4A IDE cannot access the additional libraries from a network path. But it can access the android.jar from a network path without any issue.

Solution: I copied the additional library folder to the current computer where I installed the B4A.
