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.

Changing the compatibility settings to Windows XP on the SWMHYMO.exe shell corrected the issue.

The error you are getting appears to be related to the installation of the Service Pack 1 for Windows 7. At this point we have no solution to resolve the issue.

However as a workaround.

Instead of creating a new data file from the SWMHYMO menu, try to open an existing model that already runs in SWMHYMO, modify it to suit your needs and resave it under a different name. Then run it.

A workaround we found for this error is to open an existing input file (.dat), delete the content except for the header and resave under a different name. Then you can enter all the commands you need for your project.

One solution that worked on Win7 Enterprise.

Copy the SWMHYMO folder and content installed in the C:Program Files(86)

Directly to your c drive. As in C:SWMHYMO

Then try running SWMHYMO by double-clicking SWMHYMO.exe from the copy on your C: drive.

This error is usually because the dat file input is incorrect. Check the Storm and Start command syntax and the End of file inputs in the dat file andin the separate storm file. Check that all commented lines are still commented out eg that no line return was introduced within a comment and found on its own line without a *

A solution that worked was to install SWMHYMO on the C drive directly.
And when hitting the run button, no input or output file should be open through the interface.
Also the compatibility settings were changed to run in Windows XP mode.
If none of the above solutions work, it is necessary to run SWMHYMO on the Windows XP virtual interface.
