COMSOL 5.1 Hotfix for Windows^® 10

To run COMSOL 5.1 on Windows^® 10 computers, please perform the following steps:

For COMSOL Multiphysics installations

1. Make sure that you are running COMSOL version 5.1.0.180. If the version number is not 5.1.0.180, then first please download and install COMSOL 5.1 Update 2.
2. Download and run the registry file, either by saving it on disk as a .reg file and then running it, or by running it directly from the web browser. To run the .reg file you need to be administrator of your system. When running the .reg file, you will get warnings from Windows and you will be asked to confirm that you want to run the file. Windows will also report to you if the registry update was successful. Choose either the 32-bit or the 64-bit version of the file, depending on your OS version:

• comsol_win10_32bit.reg (32-bit)
• comsol_win10_64bit.reg (64-bit)

Note! If you later re-run the COMSOL Multiphysics installer, you will have to also download and re-apply the registry file.

For COMSOL Server installations

No changes are needed.

For COMSOL Client for Windows^® installations

Download and install the 5.1.0.181 version of COMSOL Client for Windows^® below. Choose either the 32-bit or the 64-bit version of the file, depending on your OS version:

• COMSOL51_client_win32.exe (32-bit)
• COMSOL51_client_win64.exe (64-bit)
