Robert,

Many thanks for this. Because of all the time and effort you have already
kindly put into seeking a resolution - I thought it best to carefully review
everything before replying. I appreciate there is a point at which we will
have done everything we can. I'm just rather hoping that a final review of
the tests you suggested might just unearth that missing link!

PROBLEM : IE Repair cannot complete cycle because of problem with DllInstall

TESTS:

1) Regsvr32 /I /n digest.dll

    - digest.dll loaded
    - problem no entry point for DllRegisterServer

2) Control tests with other 2 *.dlls in Section 500

    - wininet.dll (success)
    - urlmon.dll (success)

Note: Checked registry and only:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnceEx\
i.e. there is no \500

3) Ran comparative *.dll version tests against Fixie.inf/Dll Help.

a) 6 mismatches where newer version corresponds with neither Fixie.inf or
Dll Help:

    - browseui.dll (6.00.2800.1400) (6.00.2800.1100-)
    - mshtml.dll (6.00.2800.1400) (6.00.2800.1100-)
    - shdocvw.dll (6.00.2800.1400) (6.00.2800.1100-)
    - shlwapi.dll (6.00.2800.1400) (6.00.2800.1100-)
    - urlmon.dll (6.00.2800.1400) (6.00.2800.1100-)
    - wininet.dll (6.00.2800.1405) (6.00.2800.1100-)

Note: No changes made yet as wanted to check whether:

- change necessary?
- can copy all (6.00.2800.1100-) files from laptop - and install afresh - or
need to download?

b) Dependency Walker records the expected presence of 3 non-existent XL
files:

   - apphelp.dll
   - userenv.dll
   - uxtheme.dll

CONCLUSION : There is definitely a problem with the DllInstall function with
digest.dll. This is due to their being no entry point for
DllRegisterServer. What is less clear is whether anything can be done to
edit and fix this? KB articles seem to suggest that this might be possible
using C++. << Frankly I don't see any advantage to using it [C++] over
regsvr32.exe>> seems to suggest that you might know a way of editing and
fixing dll entry points etc without resort to C++? If there is a way of
using Regsvr32.exe and Dependency Walker to fix the entry point issue etc
without resort to C++ - then that would be brilliant! Once again, thanks
for all your help.

Denis
