Hi,
I remember asking a while back how to force a machine not to want to uninstall a previous installation of V-Ray. But I can’t find the email/forum post describing how to do this.
How can I find the file which holds this information on Linux?
I recall I would be able to delete this file, and then the V-Ray installer wouldn’t ask me to uninstall a previous version, right?
PS. I know what I’m doing 
You can try to remove the two lines in the file /var/log/chaos_installs that look like this and are meant for your version of Maya:
V-Ray for Maya 2014 for x64=/home/tpetrov/software/vray_install/maya2014/additional
V-Ray for Maya 2014 for x64=[UN]/home/tpetrov/software/vray_install/maya2014/additional/uninstall/installer -uninstallApp="V-Ray for Maya 2014 for x64" -log="/home/tpetrov/software/vray_install/maya2014/additional/uninstall/install.log"
Thanks, that worked perfectly!
