Can't install Reflector 1.1.5 or 2.07BETA

[supabil]

I have 3 computers 2 x W10 and 1 x W11. When I try to load Reflector 1.1.5 or Reflector 2.07BETA, one W10 computer only shows the first 2 lines of the install scripts than drops out the other computer (Running same S/W level loads perfectly!. The W11 computer like the failing W10 computer shows the first two lines of the install script then drops out I can and am using Cobain Backup 11 successfully on the failing computers.
I looked at the event viewer and there was only 1 critical error in the time frame of my installs and that was a kernel error. Other errors were similar, nothing to do with Reflector.
Naturally I would prefer to use Reflector. Any ideas?

Try re-installing the .net framework 4.81 to see if there is some problem with it.

I am having trouble with the Forum it keeps seizing! I have reloaded the .net 4,8.1 on one of the W10 computers with no change. On the W11 computer it won't load it because it says there is a later version on the computer!

I have managed to post using the computer that is running Reflector and i don't keep getting the wait message which is interesting.. I have reloaded one of the computers that is failing with I imagine the latest version of 4.8.1, The W11 Computer won't load as there is a later version on the system. I even reloaded the system to the latest windows version using reset with no change. I think have included a video of the steps taken and the result. Hoever, I'm not sure it worked!

You you find some error logged in the event viewer?

Just ran Reflector install again (14:55pm). In the event viewer there has been no critical errors and only 1 other error in the last 24 hours, which was to do with the kernel, but outside the times of the install.

Try deleting The HKEY_LOCAL_MACHINE\SOFTWARE\CobianSoft\Cobian Reflector key before installing if the key exists.

Deleting HKEY_LOCAL_MACHINE\SOFTWARE\cobiansoft\cobian reflector, seems to have done the trick!
I have now installed Reflector 2.1 on one of my 3 computers.
Thanks for all your help
