WINEDEBUG=+relay,+tid,+seh,+msi wine AdbeRdr90_en_US.exe >>log.txt 2&>1

Performed a trace install through all dialogue boxes clicked via:

WINEDEBUG=+relay,+tid,+seh,+msi wine AdbeRdr90_en_US.exe >>log.txt 2&>1

I found where DefragmentFiles was called as close to the backtrace as possible,
took a few thousand lines prior (starting at line 35264316), as well as a few
hundred after the stack dump (ending at line 35271000) and attached it. The
original file is 36830321 lines long, 2.8GB in size.

I did notice instances of DefragmentFiles as early as line 7896575 which
suggests that it is checking for defragmentation throughout the install
process. Makes a lot of sense to do so. However, I haven't figured out how
towards the end of the install the DefragmentFiles custom action is causing the
divide by zero error.
