An Error Occurred when Running SWMHYMO

Question

Accepted Answer

The following problem is usually resolved by installing the patch

Shymo.xxp. see instructions below:

That error is typical of either not having the patch installed, or perhaps not having compatibility mode setup. Please follow the following steps:

 	To run SWMHYMO v4.02 on Windows 7, please install the patch available for free. Download the Shymo402.zip folder and unzip it to extract the file (exe) this file is the Windows 7 patch. You will be replacing the .exe in your program files with this new one.
 	Make sure that SWMHYMO was installed from your installation file (Download) directly on the Windows 7 operating system.
 	To update SWMHYMO with the patch, please go to your SWMHYMO installation folder and rename the file exe to xshymo402.exe file to make a backup copy of the original.

The file is usually found in the program files folder in Windows as such:

C:Program Files(x86)SWMHYMO shymo402.exe

 	Then copy the patch downloaded from the website (shymo402.exe), to that same folder.

C:Program Files(x86)SWMHYMO shymo402.exe

SWMHYMO should now run natively on your system.

To test it, please double-click the shell: swmhymo.exe.

Then try to run an example file.

When you run your updated version, your SWMHYMO models printouts (.sum and .out files) will show version 4.05.

This is an indication that you did your update correctly.

Some users have also needed to set the software in compatibility mode, see the following steps:

 	Change the compatibility settings for running SWMHYMO by running the SWMHYMO engine in Windows XP mode.

->Right-click on shymo402.exe (the new one you just copied in the Program folder as per the instructions sent with the patch)

->Select Properties.

->Select the Compatibility tab

->Checkmark and choose: Run this program in compatibility mode for:

Select: “Windows XP (Service Pack 3)” from the dropdown menu

 	Change the compatibility settings for running SWMHYMO by running the SWMHYMO GUI in Windows XP mode.

->Right-click on SWMHYMO.exe (in the same directory)

->Select Properties.

->Select the Compatibility tab

->Checkmark and choose: Run this program in compatibility mode for:

Select: “Windows XP (Service Pack 3)” from the dropdown menu

Test SWMHYMO. If it still doesn’t work, try rebooting your computer then test SWMHYMO again.
