BIM Software Tips: How to Change the Autodesk Product Installation Source
Managing the registry to prevent tampering is quite complex. It involves updating application values such as LastUsedSource and the network Windows Installer packages. Each installed Autodesk product has its own set of registry keys. You can find them in the Windows registry at the following locations:
HKEY_CLASSES_ROOTInstallerProducts<Product GUID>SourceListLastUsedSource
HKEY_CLASSES_ROOTInstallerProducts<Compressed Product GUID>SourceListNet1
Note: Every product has a unique UID, so you may need to search for it by the product name.
The LastUsedSource key data typically follows these formats:
Example for a local or mapped drive:
n;1;F:Folder1Folder2mySource
Example for a network UNC path:
n;1;\Server23Folder1mySource
Example for USB or DVD media installation:
m;1;MyDiskY:Folder1mySource
The network value “1” in the key only requires the UNC path or the original local path to the installation source.
Examples of installation paths:
Local installation:
C:Autodesk<Product>AutodeskProductName
Network UNC path:
\Server23Folder1mySource
Keep in mind that the installation location may vary depending on where your software was originally installed.
If the original installation source is no longer accessible, the only way to resolve the issue is to manually edit these registry entries and update them with the new location in the formats shown above. This avoids the need to uninstall and reinstall the software.
