RunInUAE troubles

[F0LLETT]

I need some help in reinstalling RunInUAE in Os4.1.

My original installation got corrupted and I don't know how. ADF or WHDload are not longer working.

I have tried renaming the olf installed drawer, or deleting it, but every time I tried reinstalling using the AmigaOS4.1 FE Pre-Release CD, I get a message saying that it found an exisiting installation. Trying to use either simple or custom installation results in lots of windows asking for the rom files, which I don't know where they are in the CD or elsewhere.

Can somebody guide me on how to delete all previous installations and reinstall from fresh?

I was also getting this Guru Meditaion when trying to run the original installation: https://drive.google.com/open?id=1gRawYdddWX2z_zFJ5i4FIwdNwbaPyKAt

The original installation worked for a few days after I installed Extras in my first run of the X5000 days ago.

Thank you.

Thats the normal install. It asks were everything is. ROMS and DISK images are in the Emulation drawer in system.
