Crash on Win7 64bit

[rabelux]

I've copied your zip to the appropriate folder but now QuickLook crashes instantly after starting.
Log:

System.IO.FileLoadException: Die Datei oder Assembly "file:///C:\Utilities\QuickLook\QuickLook.Plugin\QuickLook.Plugin.HelixViewer\QuickLook.Plugin.HelixViewer.dll" oder eine Abhängigkeit davon wurde nicht gefunden. Der Vorgang wird nicht unterstützt. (Ausnahme von HRESULT: 0x80131515)

Hi @rabelux, could possibly be related to this issue: QL-Win/QuickLook#1
Give that a shot and let me know how you get on.

[rabelux]

Nope, QuickLook has been working fine. After removing your plugin-folder from QuickLook.Plugin it is all back to normal, so unfortunately it is your plugin. Log also mentiones your dll in the second line: Dateiname: "file:///C:\Utilities\QuickLook\QuickLook.Plugin\QuickLook.Plugin.HelixViewer\QuickLook.Plugin.HelixViewer.dll ---> System.NotSupportedException

EDIT:
sry for my quick response, haven't read the issue properly. I redownloaded, made sure to check the trust-this-zip-box, unzipped and issue persists

[jeremyhart]

I just tried downloading it and was able to replicate the issue, causing QL to crash.
It was fixed by unblocking the zip file before extracting it.

3rd update:
deactivating antivirus and using winrar to unzip indeed resolved the issue!
realized that trusting the zip on win 7 seems to do nothing as it is untrusted as soon as the property-window has been closed and reopened :S
