But, in TestComplete IMPOSSIBLE to run CBT ==> the following error is displayed: << No valid license was found on the CrossBrowserTesting.com server for the specified user account.

Re: Windows 7: installation TC 14.40 failed error 1603 Hello, thank you Marsha for your answer. 1- I am on a WINDOWS 7 machine, I install and uninstall all versions of TC / TE up to version 14.30 without any problem. However, the installation of version 14.40 or 14.50 never succeeded. 2- I did a second installation test on a second WINDOWS 7 machine, the result is identical, that is, until version 14.30 no problem, but, versions 14.40 and 14.50 without success. 3- I did a 3rd installation test on a 3rd WINDOWS 10 machine: with success 4- I did a 4th installation test on a 4th WINDOWS 10 machine: with success regarding the recommendations of the site https://support.microsoft.com/en-us/help/834484/you-receive-an-error-1603-a-fatal-error-occurred-during-installation, nothing has changed . Is this problem perhaps related to the incompatibility of TC / TE 14.40 / 14.50 with WIndows 7? and yet on the website https://support.smartbear.com/testcomplete/docs/general-info/system-requirements.html everything is compatible. Thanks for your help. Regards, Windows 7: installation TC 14.40 failed error 1603 Hello, my PC configurations: - Windows 7 service pack1 - Intel pentium 3 GHZ - 4 GB RAM - OS 32 and 64 bit OS ==> installation of all versions of TestComplete until 14.30: OK However, the installation of version 14.40 of TestComplete does not succeed ==> display of Error 1603. NB: I installed on 2 different workstations in Windows 10 ==> OK, and on 2 different workstations in Windows 7 ==> KO. Thanks for your help Very cordially, SolvedRe: Cannot read property of undefined. That is to say: The error appears: 1- when a variable (Excel file) is used in the same script (function), we can not update the same file through: var conn = Sys.OleObject ("ADODB.Connection"); conn.ConnectionString = "Provider = Microsoft.ACE.OLEDB.12 ...... var Request = "UPDATE [Tab1 $ A" ....... "] SET F1 = ..... conn.Execute (Application); conn.Close (); 2- Or, when using Data-Driven Loop to browse a variable (Excel file) and we use a script (function) to update this same file through var conn = Sys.OleObject ("ADODB.Connection"); conn.ConnectionString = "Provider = Microsoft.ACE.OLEDB.12 ...... var Request = "UPDATE [Tab1 $ A" ....... "] SET F1 = ..... conn.Execute (Application); conn.Close (); 3- Bypass Solutuion: go through a temporary variable (Excel file) My Excel File -> Temporary Excel File Temporary Excel file -> My Excel file Re: Cannot read property of undefined. Thank you very much for your help. in fact the problem comes from the fact that the Excel file is used in "Data-Driven Loop" as a variable, then, used in the "Script" as an external file. cordially Re: Cannot read property of undefined. By the way, the error "Can not read property of undefined." after the appearance of the error "MS Office Access Data Engine" that I can not solve. thank you for your help Re: Cannot read property of undefined. Yes that's right, even restarting the PC and TestComlpete, the problem reappears, and this is the first time I've had it for 3 years, I use version 12.20. Re: Cannot read property of undefined. I do not understand, everything worked and suddenly TestComplete starts messing around: TypeError Can not read property of undefined. function Test1 () { // Executes the specified code snippet. BuiltIn.ShowMessage ("yyy"); // Executes the specified code snippet. Log.error ("uuuu"); }
