When installing a Bentley Hydraulics and Hydrology application, the following error message occurs

"Error 1935.An error occurred during the installation of assembly"

[Problem ID#: 85087]


This is related to issues installing the Microsoft Visual C++ Redistributable that is included with the installation.

This is a prerequisite that comes from Microsoft.

The Bentley Hydraulics and Hydrology installation files are self-extracting, meaning that the different executable files within the main setup file are run automatically without you needing to install the different components individually. However, the individual files can be extracted and run individually. For this issue, try installing the file "vc9redist_x86.EXE" (the name might be slightly different depending on the application) by extracting it from the installing file. If you run into a similar error, you will need to contact Microsoft for further support.

If the file installs successfully, then try installing the Bentley Hydraulics and Hydrology application again.
