the RC-WinTrans command line tool does not work on my Windows 7 (64bit). It was OK on my Windows XP.

I get the following error message when running the "rwtcmd.exe" (with any command):

"Unable to cast COM object of type 'RCWinTrans.ApplicationClass' to interface type
'RCWinTrans.IDualRWTApp'. This operation failed because the QueryInterface cal
l on the COM component for the interface with IID '{B3DB1E36-4E42-4D4C-A738-1DDE
AA83A381}' failed due to the following error: Library not registered. (Exception

I'm using RC-WinTrans 9.1 from January 2011.

Can anybody help ?

Thanks, Samuel

Hello Samuel,

this is a known problem. During the installation of RC-WinTrans on Windows 7 the RC-WinTrans application object is not successfully added to the Windows 7 registry.

Check the "Known Issues" section here in the forum for a description of the problem and its solution:

From my experience, this issue can be avoided by running the installer "as Administrator" by right-clicking on the installer and selecting "Run as administrator". This should be a fairly easy to fix in the InstallShield project by setting the required execution level of the installer to "Administrator".

Hello schaudin team,

the suggested solution works on windows 7 32bit but does not work on windows 7 64bit (Tested on serveral machine, has nothing to do with side by side installation rc-wintrans 7) The interesting thing is that the regcheck tool seems to be happy with the installation: Application Object and Type Library are found, at least the way the test tool looks for them.

Trying to create the IDualRWTAppPtr Application Object

[font=Consolas]IDualRWTAppPtr spApplication;
hRef = spApplication.CreateInstance(L"RC-WinTrans.Application");

leads to "Server Execution failed" Error 0x80080005

Neither RC-WinTrans.Application are registered within HKEY_CLASSES_ROOT nor the associated CLSID {06CD89C8-AE90-469D-892E-2F9E41236B7A}
It seems as if the HKEY_CLASSES_ROOT stays absolutly untouched while manually trying to register the com automation stuff as mentioned within http://www.schaudin.com/forum_srv/topic24-windows-7-com-object-and-command-line-failed.aspx

Using current RC-WinTrans 9.2 Global (April 2012)

Help appreciated
