Dopushlp.dll error message

Hello Support,

running DOPUS 10.5.2.0 (4913) from an USB stick gives the following (german) error message:

E:\DOPUS\dopushlp.dll ist entweder nicht für die Ausführung unter
Windows vorgesehen oder enthält einen Fehler. Installieren Sie das
Programm mit den Originalinstallationsmedien erneut, oder wenden
Sie sich an den Systemadministrator oder Softwarelieferanten, um
Unterstützung zu erhalten.

After clicking OK DOPUS works without problems.

I created the stick on Win8 (64bit), DOPUS 10 with 32 and 64 bit support but the
message is very irritating. Please resolve this.

Regards
Michael

[ul][li]Please test the digital signature on E:\DOPUS\dopushlp.dll to verify that the file itself is not corrupt.

[/li]
[li]Is E:\DOPUS where the USB copy is being run from, or is it an unrelated folder?

[ul][li]It might be left over from a previous USB copy.[/li]
[li]Or it could be the drive letter which the USB device used in the past but isn't using today.[/li][/ul]
[/li]
[li]When does the error message appear?

Is it as soon as you launch Opus?

[ul][li]How are you launching Opus?[/li]
[li]Is Opus configured to run any commands at startup? (Under Settings - Preferences / Launching Opus)[/li][/ul]
Or is it later on, when you do a particular action?

[ul][li]Which action is triggering the message?[/li][/ul]
[/li]
[li]Which version of Windows are you running the USB copy on? (It's exported from Windows 8 64-bit, but is it being run on the same OS, or on another OS?)

[ul][li]If it's Windows XP, which service pack is installed?

[/li]
[li]If it's Vista or above, what happens if you try to do something that requires UAC elevation?

e.g. Create a new folder under C:\Program Files. On a USB install, that should show an extra prompt, asking you to allow a component to be registered. (The component is dopushlp.dll, although it is not mentioned by name. If you aren't prompted, it may already be registered, and the registration may point to an old or incompatible version of the DLL. If so it is easy to fix.)[/li][/ul][/li][/ul]

The digital signature is ok.
E:\DOPUS is the folder on the USB stick.
The message appeares after the first start of DOPUS.
I'm launching DOPUS via the windows start menu -> Ausführen... -> E:\DOPUS.exe
Start von Opus -> Autostart is set to "Jenen Lister öffnen, der beim letzten Beenden des Programms offen war."
I'm running DOPUS on Windows 7 32bit, it's exportet from Windows 8 64-bit with support for 32- and 64-bit.
No UAC is neccessary.

Thanks for the answers.

If you run E:\DOPUS\x86\dopus.exe does that work without error?
