Microsoft Visual C++ 6.0 and Visual Basic 6.0 can generate debug info as an external PDB file. AQTime needs debug info for profiling and, like any application, it will need Microsoft's DBGHELP.DLL in order to read this info from PDB files. This message is displayed when the DBGHELP.DLL version found is not current. To solve the problem, update the DLL version and make sure it is accessible to AQTime. Currently, AQTime uses DBGHELP.DLL ver. 6.12.2.633. It is included into AQTime’s installation package.
