If you are using eDrawings 2006 SP04, this is a known issue.
It will be fixed in SP05. In the meantime, use the attached
registry file to fix the eDrawings file associations.
Note : This is a registry fix, so use with caution (backup
your registry before use) and use with Windows 32-bit systems only.
Do not use with 64-bit systems.
I can't seem to associate the .edrw extension with edrawings
2006. If I right click on a .edrw file and point it to edrawings,
it will open with Adobe Acrobat. Has anybody else seen this or does
anybody know what the problem is?

Hope this helps,
