error 5 showed up when migrating from XP to win 7

I am not the developer of this code nor a VB developer but have been tasked to figure out why this code is failing on windows 7 when it was working on XP.

error is occcuring here:

Dim X as Long
X=1

Do While (x < Len(csNewRTFText)
ts.Write Mid(csNewRTFText, X, 256)
x= x+256

Loop

I am wondering if there are some libraries missing in the new win 7 enviornment that are needed. I found the original vbp file and it lists references to dlls that are not on the machine.

I am wondering if these are no longer needed and the problem lies else where.

You can't just copy an EXE to a new machine and expect it to work.

MSSTDFMT.DLL requires deployment.

ProtoView\DataTable8\PVList.ocx#ProtoView ListBox Control is some 3rd party OCX, and also requires deployment.

MSO9.DLL plus MSWORD9.OLB imply that Office 9 ("2000") needs to be installed first.
