OK. Thanks.
- I copied BB folder from drive C to drive E
- After that I deleted BB folder from drive C
- The I installed BIAB from the external disk to drive E with no problem

Yesterday when BIAB installation collapsed it did install HI-q instruments and Sample Tank. It seems that they are on drice C in Program Files. Now I tried to install them to the drive E but installation stucked. I tried to change the folder to E but this is what is says:
"You must enter a full path with drive letter f. ex C/APPS or a UNC path in the form: \\server\share"

What should I do?

I will delete the stuff from drive C after I get things completed.
