Embedded visual studio object scripts not functional upon MS-Office migration from 32- to 64-bit

I am using Mathcad Release 15.0 and DatecodeM050

After MS Office migrated from 32Bit to 64Bit (on a 64Bit machine) a visual studio object script embedded into the MathCAD sheets is not available anymore. As a consequence MathCAD15 outputs an error message "Cannot launch server application". This omits scrolling and other work in the sheet so that in the end it is unusable.
