Some Microsoft Search products require additional setup steps as described below:

Windows Search:
When integrated with Windows Search, DWG IFilter uses a temporary directory to process DWG files. Due to Windows Search security restrictions, IFilters are not able to utilize the default system temporary directory. Therefore, DWG IFilter must be set to work with a user specified temporary directory. To change the DWG IFilter temporary directory's settings:
- Stop Windows Search service.
- Open registry key "HKEY_LOCAL_MACHINE\SOFTWARE\IFilterShop\DwgFilter"
- Add new String value named "TempPath" and enter the full path to the new temporary directory. If this value is missing, empty or the path is not pointing to a valid directory, system temporary directory will be used. Please make sure that "Users" or "Authenticated Users" Group has "Full Control" permissions to the custom temporary directory.
- Start Windows Search service.
How to Uninstall
If you ever have to uninstall DWG IFilter application you can easily do it using any of the following methods:
- Through "Add/Remove Program". Open Control Panel ->Add/Remove Program. Select "IFilterShop DWG IFilter" in currently installed list. Press "Remove" button.
