I have recently cleaned out my 2nd XP Laptop which was getting very slow I use it as a backup to my MacBook VM Windows 8.1 I have made numerous attempts to install V5, I keep receiving the following message ; Cannot find import ; DLL may be corrupt or missing or wrong version File “mfc 100.dll”, error 126. I have installed V4 with no problem, is the V5 installation disk faulty, prior to this the disk was only used twice and has been kept in its box in a warm room. Any reply would be appreciated John
