Using windows 7 that only uses the version 5 installer it then corrupted my dll's somewhere on the pc ... guess system or system32 folder or something, i renamed the folder back to the original state it was and got this error I decided to not mess with it further, to sort it later i had some work to do so started working on charting software, somewhere during my work the same day it came up that i needed to install Java on Chrome to view charts. "Windows installer service could not be accessed. This can Occur if the Windows Installer is not correctly installed.
