Hello all,

When an application crashes, it will generally be caught by Dr. Watson and create a dump in the same location as the Drwtsn32.log file. This is the dump file we can open using the Debugging Tools for Windows. To do this, run Windbg.exe from the Debugging Tools folder. Click File – Open Crash Dump and browse to the.DMP file in question. With the last update (packages updated on 3/16/2021) I have a problem with xelatex, while pdflatex or lualatex both work fine. AppData Local MiKTeX 2.9 miktex log initexmf.log shows: 2021-03-17 18:46:46,891+0100 FATAL xelatex.core - Die Speicher-Dump-Datei konnte nicht gefunden werden. 2021-03-17 18:46:46,891+0100 FATAL xelatex.core - Data: fileName='xelatex.fmt' 2021-03-17 18:46:46,891. I went looking into the directory - and the file is there. But TeXWorks tells me: This is pdfTeX, Version 3.1415926-1.40.11 (MiKTeX 2.9) miktex-pdftex.exe: The memory dump file could not be found. Miktex-pdftex.exe: Data: pdflatex.fmt I also looked for miktex-pdftex.exe, and I found it in the bin. Problem is, somehow I didn't got a new logfile.

I upgraded from Miktex 2.7 to 2.9 yesterday on my Vista system [I'm an
experienced LaTeX user currently working in industry. Needed to write
a technical paper and went back to LaTeX] and it's been a nightmare.
Your help is much appreciated.

Here's a chronicle of my issues:

1. After installing, I tried compiling a simple document [my own]. It
said something about not finding hyperref. So I tried updating MikTeX
using the update manager, it didn't work. When I ask it to install the
missing package via package manager, [which I'd set to install
missing packages on the fly], it gave an error like this:

The results I got were: This is pdfTeX, Version 3.1415926-2.4-1.40.13 (MiKTeX 2.9 64-bit) pdflatex: The memory dump file could not be found. Pdflatex: Data: pdflatex.fmt After some research, I ran Settings (Admin) and confirmed under the Formats tab that pdflatex is not excluded.

'Windows API error 5: Access is denied.'

Did a reboot but no luck in making it go away. A Google search showed
nothing directly relevant but some reports that Adobe is an issue so
uninstalled that [I had Adobe Reader X]. Still no luck.

2. I then thought it was an installation problem and tried to
uninstall and now it gives me the following error:

'The operation could not be completed for the following reason:
The IniTeXMF executable could not be found'

3. I then made sure my anti-virus system {Norton} was not blocking and
and that was fine. Tried a recompile of the basic tex file and here's
the message in TeXworks:

-------------------------------------------------------------------------------
This is pdfTeX, Version 3.1415926-1.40.11 (MiKTeX 2.9)
miktex-pdftex.exe: The memory dump file could not be found.
miktex-pdftex.exe: Data: pdflatex.fmt
-------------------------------------------------------------------------------

4. Tried to run update/package manager again and the former says 'no
new updates' while the latter hangs ['Not responding' message].

From what I can tell, the installation is broken but I don't know how
to uninstall or fix it. Please help!!!
