I did the Vista--> Windows 7 (home premium) upgrade having had NSI 09 installed under Vista.
The upgrade went through okay but the system is bluescreen crashing everytime.
NSI seems to be the problem but it doesn't let me uninstall as it's not compatible with Windows 7. Also, I tried updating to NSI 10 as per recommended solutions but it doesn't let me finish that update either.
I'm now running my laptop in safe mode as it's the only way to not crash.
Any help & solution greatly appreciated.
