How to Delete Engineering Libraries

If you receive an error, while using a Bentley Hydraulics and Hydrology product, that references engineering libraries then the following steps will allow you to revert back to the original.

**Before performing the steps below please make sure to close the application**

Steps

1. Navigate to this location: C:\Users\<user name>\AppData\Local\Bentley\EngineeringLibraries\

2. Delete the EngineeringLibraries.sqlite and any .bak or backup files for this database file.

If you don't see the files or folders listed above, make sure they aren't hidden. In some instances, the …\AppData folder has a Read-only setting which will cause you to get an error that you are trying to open a Read-only database. Setting permissions on the AppData folder to Everyone Full Control will clear this error.

3. Open the program

Note: For PondPack, you would browse to C:\Users\<user name>\AppData\Roaming\Bentley\EngineeringLibraries\ . The engineering library file is engineeringlibraries.mdb.

If the error is still generated, contact Bentley Technical Support and they can provide a clean copy of the engineering libraries file.
