When installing the modtran software, I found that there is no response after clicking the setup.exe file. I guess it may be because the software version is too old.
Workaround: \color{#FF0000}{Solution: }Solution: Install after entering the safe mode, and then exit after the installation is successful.
Enter safe mode:
WIn+R, enter the command [msconfig];
After checking [Safe Boot], click OK;
3. After restarting, click setup.exe normally to install.
exit safe mode:
WIn+R, enter the command [msconfig];
Check [Normal Startup], then uncheck the box in front of [Safe Boot] , and click OK;
