I just completed a full system re-install (Cubase 6.5 64 bit on Windows 7 64 bit), including a re-install of Virtual Guitarist v1.0.0.0. Initially, I did run into the apparent installation hang at the “update registry” stage, as reported earlier in this thread. However, after much experimentation, I found that just being patient for 10-15 minutes would be rewarded with the installation suddenly coming back to life and progressing to the next screen (without any intervention by me!). The installation then completed without problems and both Acoustic and Electric VST are now running just fine on my system. Very happy about that, I would have hated not being able to use them anymore, they were a key instrument in many of my earlier projects. Just thought I’d share.
