Completed installation of PG 1.30 on Windows XP-xps2 Home with no problems during installation and setup. Did do a SAFE MODE uninstall of PG 1.2 prior to installing PG 1.3; however, that was my choice. Not sure whether it was necessary. Was able to save away pguard.dat file from c:\Windows\System32 folder and then re-install to recover all my previously installed programs for protection. No Kernel mode errors on booting, etc. Lookin' good thus far!
