Hello,

I was using Win7 on Win7 host and there was no problem, however after I have upgraded to 4.1.20, I can't use Guest Additions anymore. I have tried to install several times,
however, still no use of mouse, screen (small), no shared folders. How can I solve the problem?

I have also restored to system to return to previous version, and this time I get an error and couldnt open any VM. And now I have installed 4.1.20 again. And Guest Additions doesnt work.

best regards,

I have uninstalled 4.1.20 and installed 4.1.8. It works fine without Share Folder Capability, trying to fix it.
