ISO file wont install

Have downloaded two different ISO,s of the game “SAS SECURE TOMORROW”
With either ISO I mount it to a virtual drive and open it, click instal and get the following error message.
Run time error (at 83.355)
Cannot open file
C:\User\(name)\AppData\Local\Temp\is-ouu4h.temp\Splash_en.b
Can anyone offer any useful suggestions?
Appreciate any help I can get.
Answer #1
Try to mount with Daemon Tools I think that would work well.
Answer #2
Which virtual drive program are you using? Try using a different one such as “Alcohol 120%” or with “Daemon Tools”. Or try reinstalling your current one.
Answer #3
Tx Binary. Just tried Alcohol 120 and exactly the same thing.Have even tried burning to CD anf loading from CD but exactly the same thing happens.As I say have tried TWO completely different downloads to get two different ISO files but the same on both.Maybe its something to do with Vista
