Same lines of code is working for an application in one machine and not working on other machine.

Have two machines with Win7 enterprise version and same version of inhouse desktop application built on WPF and Python.

Using .Net Framework version as 4.5.51209, as checked in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full

 

Using Testcomplete v11.0644, have a scnerio to select and right-click an item from a ListBox WPFObject. But ClickItemR(x) is working in one machine and not on other. Below is the error displayed.

 

Possible reasons:
1. The application stopped responding.
2. The application was compiled incorrectly (see the Open Applications topic in the help system).
3. An error occurred in TestComplete.

Technical information:
442 0x80070057 (The parameter is incorrect.)

Any suggestions please.

    Hi Dhirendranaga,

     

    Do you use the same TestComplete version on both machines?

    Does the project the same? Check the project settings in the projects on different computers.

    I have a similar issue with a similar error.  However, I am only experiencing this problem in Chrome 49.0 with TC 11.30.  I have scripted several tests in Chrome, so overall it is working fine with TC 11.30.  In this scenario, there are 3 radio buttons displayed on the page.  With the exception of the first radio button, which displays a subordinate page with 5 radio buttons, it works.  However, when the first radio button is selected, the script fails after selecting it with a similar "application stopped responding" error as follows (please see additional comments below error message):

     
    Possible reasons:

    2. The application was compiled incorrectly (see the Open Applications topic in the help system).
    3. An error occurred in TestComplete/TestExecute.

    I have rerun the exact test in FF & IE and both run successfully.  I also decided to code a keyword test in Chrome to see is that also failed and it did, with the same error. :(
