AutoCAD Error - Unable To Save To Drawing

Issue: Get an error message "Unable to save to drawing . Drawing saved to

Quick: Set .bak file for that drawing to all inherited rights and be sure it is not read only.

Visual/Learning:
Very strange problem showed up. Engineer trying to save a AutoCAD drawing got the following error message:

Saving as any other name works fine but every time he tried to save as that name it removed both the .dwg and .bak files and saved the file as .tmp file.

Verified this behavior on 2 different machines.

Found a link to some information that was helpful stating at the end that the .bak file might be read only.

I check and the .bak file was not read only, but when I right clicked the file and checked the security settings for the file it was not inheriting security from the folder. I set the .bak file to inherit security and now it works.

Still odd because I would think that with the .bak file coming and going it would get the correct security but not the case for some reason.

Uninstall Problems With AutoCAD Civil3D

Issue: After uninstalling AutoCAD Civil 3D 2008 we were unable to re-install because the installer thought that the application was already loaded.

Quick/Visual/Learning:
After using add/remove programs to uninstall AutoCAD Civil 3D we had a issue trying to re-install. The box for installing Civil 3d was grayed out. The text under the option said that it was already installed.

After searching for and deleting files from the hard drive and Autodesk registry entries the problem still persisted. In the end the fix turned out to be that we needed to rename or delete the installer directory for the application.

The directory for Civil 3D is the one in the picture above. Look for it in either:

C:\WINNT\Installer\{2CD6BBA0-17C8-4789-9B9B-B36F7E815F6A}

OR C:\Windows\Installer\{2CD6BBA0-17C8-4789-9B9B-B36F7E815F6A}

After renaming the diretory the installer no longer saw the application as already loaded and allowed to check the installation box.

Found this tool "Window installer Cleanup Utility" that is supose to do the cleanup for you.
