Why my shared component dosn't work?

Hi, I created a COM component .dll using deploytool to make my matlab function callable in a VB application. It works well in my pc which has the Matlab software and the Microsoft Visual C++ 6.0 installed. But it doesn't work in others PC without Matlab after I unpacked the .dll file and MCR. The dev PC is a 32bit with Windows XP, while the target PC is a 64bit with Win7. Furthermore I’ve successfully registered my library and installed Visual Studio redistributables, but it didn’t solve the problem. By running the dependencywalker and profiling the mwregsvr.dll I’ve got following errors: Error opening file. The system cannot find the file specified: DGIMAGER.DLL; GPSVC.DLL; IESHIMS.DLL; XCEEDZIP.DLL;

Thank you very much for your answer.

Regards,
