Summary
Error
The script <script_name> is from LoadRunner version <12.56.0.985>. This does not match the load generator <LG_name> version, <12.55.0.0>
Cause
This warning appears while running tests in PC 12.56, even when the script was developed in VuGen 12.56 as well.
What happens is that 12.56 is an update upon 12.55, as a matter of fact, in control panel we see Performance Center host (HPE LoadRunner) build Version 12.55.646.0, But the number .646.0 means the update is installed and can be seen in windows Updates as LoadRunner 12.56 Update.
Fix
This warning does not affect a test during a load test scenario, it is just a cosmetic issue that can be changed to be not display at the script level.
1 – Open/Edit the .usr file into the script folder with a text editor
2 – Look for the label “LastModifyVer”
3 – Change the value 12.56.0.985 for 12.55.0.0
Note: It must look as, LastModifyVer=12.55.0.0
4 - Save the changes and upload the script again
