Last night i was trying the 4.7 Version of PVC but after following their instruction i wasnt able to get the PVA installed (Parallels Virtual Automation) on Centos 6.3 minimal .
Before you start installing PVC, first install these packages..
Centos 6.3 32Bits
pciutils perl bc ed procmail mailcap pkgconfig libstdc++.so.5
Centos 6.3 64Bits
pkgconfig pciutils perl bc ed procmail mailcap compat-libstdc++-33.x86_64
Then install PVC as the instruction says.
