If so this is what you need to do to eliminate the BSOD problem with EIS9

What was the BSOD Error Message? Was it IRQL_NOT_LESS_OR_EQUAL ?
If it was, then exterminator20's suggestion is the correct one for W7 SP1. On the Emsi support forum this is the solution in 90 % of cases - but you really should post your issue on the Emsi support forum.
The IRQL_NOT_LESS_OR_EQUAL BSOD is most commonly caused by Microsoft's netio.sys driver and is not caused by EIS.
Microsoft confirmed this issue a while back and has provided the Hot Fix, but does not include it with Windows Updates.
If you are missing this Hot Fix make sure you install the correct version for your system: x86 or x86-64.
If you get a BSOD immediately after the required installation reboot then that is an entirely different issue. Recently, Emsi made some changes to its drivers but they have been very stable in closed-beta testing.
EIS BSODs are not widespread, but are rather most commonly centered around either an existing install or incomplete uninstall of VirtualBox - or caused by Microsoft's netio.sys driver.
A few BSOD's have been caused by obscure 3rd party drivers, reported to Emsi via its support forum, and fixes applied...typically within days.
With the vast amount of software out there everyone needs to keep in mind that incompatibilities can creep up at any time...and cause a BSOD.
If anyone has won an EIS license then why not download EIS and evaluate it on your system using the 30-day trial.
Asking whether or not EIS will cause a BSOD on your specific system is a waste of time as no one knows; it might or it might not - and EIS' reputation for causing BSODs is not warranted. Emsisoft has received virtually all of the blame for Microsoft's screw-ups with some of its drivers...just like so many other AV vendors have been unjustly blamed because of Windows issues.
I don't understand why there is a fear of BSODs. If you configure your system to save mini-dumps then you can post your issue on the Emsi support forum with the dumps. It is extremely likely that Emsi staff will determine what happened, why and then provide you with a fix.
