Another two annoying admin quests

   Today I will share problem decisions connected with Visio Viewer and WinDjvu.

   Let's start with Visio. I had to install Visio Viewer on client computers, and one of them while opening visio schemes showed blank IE tab with red cross. After googling I found that register key (HKLM\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{279D6C9A-652E-4833-BEFC-312CA8887857}) removal gave sufficient result.

   Another problem happened while right-click on file took place. First of all I thought that AV check took a long time, but after using procmon I understood that there was no check after first time. Some time I spent on russian forums and found out a good piece of advice. If you know russian you can check this.
In brief I made several steps to achieve my goal:
1. I found register key HKEY_CLASSES_ROOT\ Applications.
2. I opened each key with "name_programm.dll" and "name_programm.exe".
3. If nothing was encapsulated in these keys I searched for empty string parameter "NoOpenWith". If parameter was absent, I created it manually.
4.  If something was encapsulated, I went down till "command" subkey was found. I checked the path which was written in default key.
5. I found that WinDjvu tried to find something on server, which was replaced a year ago. I deleted this key from the beginning "WinDjvu.exe".
6. Happy users - calm admin!
