helper.exe stopped working when about to write

[truboxl]

Maybe related to #21 Windows 7 Ultimate SP1 x64 All the VC++ installed...

When Media Writer starts to write, a Windows Error Report dialog shows up saying "helper has stopped working"...

Tested on Workstation option and Custom ISO option, others didn't test, download speed and verifying process (uses ~11% CPU?) are very slow, so assume they will hit the helper.exe problem eventually...

Closer inspection with Process Explorer shows helper.exe runs this command (this is Custom ISO option): "C:\Program Files (x86)\Fedora Media Writer\helper.exe" write D:/Downloads/F24-x86_64-MATE-20161023.iso 1

Running it on cmd.exe returns -1 and then the same WER appear...

Which version were you running? Where did you download it from? I don't understand the bits about the downloading and verification speed. Did you write a custom image or one downloaded by the FMW directly? Did the error happen immediately after you started the writing process or after a while?

Version is 4.0.0, downloaded from the release page

The downloading process is through Workstation option, it would be better if there's an option to use a locally downloaded ISO and skip downloading wholly (that would be Custom ISO option I believe)... Just blame my ISP's slow connection...

But after downloading, verifying the ISO took a long time to finish and it uses ~11% of my CPU, dunno why it won't use up all the CPU...

The real problem is after all that time went into preparing, it stopped with that WER dialog after pressing Write. My USB just barely flashes... Nothing has written. Tried another one USB drive, same problem.

EDIT: Fix my Engrish

Thanks for the description, I'll look if there's any reason for that error you're describing. It's not related to #21 though, I'd say.

The check takes only 11% of your CPU because it's reading the data from your disk which is probably not supplying the data fast enough to load the CPU to 100%.

As I mentioned in the other issue, I'll have to get a Win7 box first to try this myself, please wait for a bit.

I'm able to reproduce this problem, going to work on fixing it today.

Just to say, thanks for fixing it :D

I'm glad it works for you. :) Please come back to report any other problem you see :)
