248. Matt Monroe's Molecular Weight Calculator under Wine on Linux

I've downloaded the source code to Matt Monroe's molecular weight calculator in the past, and having replaced wsearch32 (+wine) with OpenChrom I figured I'd go online, download it and see what Mono can do for me. I had a vague recollection that the source code was only freely available online for a short while, and as it turns out I couldn't find it this time.

Anyway, not finding the source code I decided to update my Molecular Weight calculator from version 6.46 to 6.49 which (finally) allows you to set the charge of an ion WITHOUT having the mass of a H+ added for each charge. It's not difficult to compensate for, but it's always confusing to new students.

1. Install Wine and winetricks, add dlls
You can either install wine from the repos (old version)
sudo apt-get install wine-bin

Or you can download a newer, unstable version from dev.carbon-project.org:

Or you can compile your own:

The mono step was a right headache and would fail unless I nuked everything winetricks and wine knew about each other/

To get winetricks and set everything up:

sudo apt-get install cabextract

wget http://winetricks.org/winetricks
sudo mv winetricks /usr/local/bin/
sudo chmod +x /usr/local/bin/winetricks
wget http://downloads.sourceforge.net/project/wine/Wine%20Mono/0.0.4/wine-mono-0.0.4.msi
wine msiexec /i wine-mono-0.0.4.msi

You're now asked whether to download and install mono...sigh...more often that not this has failed in the past.

winetricks vcrun6sp6

Download the file from the browser window that just opened

cd ~/.cache/winetricks/vcrun6sp6 

mv ~/Downloads/Vs6sp6.exe .
winetricks vcrun6sp6
winetricks corefonts
winetricks riched30
wine uninstaller --remove '{E45D8920-A758-4088-B6C6-31DBB276992E}'
winetricks dotnet20
cd ~/.cache/winetricks/dotnet20/
mv ~/Downloads/dotnetfx.exe .
winetricks dotnet20

Ignore this error. Installation will take a while after that. Have patience. Like 10 minutes kind of patience.

And finally:

winetricks wsh57

2. Download the molecular weight calculator and install
If you go to http://www.alchemistmatt.com/mwtwin.html
you get redirected to here: http://omics.pnl.gov/software/MWCalculator.php

cd ~/tmp
mkdir molw
cd molw/
wget http://omics.pnl.gov/installers/MolecularWeightCalculator_Installer.zip
wget http://omics.pnl.gov/installers/MwtWinDll_SourceAndSupportingDLLs.zip
ls *.zip|xargs -I {} unzip {}
unzip MwtWinDll_Source_v3.4.4518.zip

You'll get some warning about Revisionhistory.txt etc. being overwritten. That's fine.

Launch the install with
wine msiexec /i MolecularWeightCalculator.msi

If you try to launch the mol weight calculator at this point you'll get an error about a missing MwtWinDLL.dll:

So sort that out:

cd ~/tmp/molw/bin
regsvr32 MwtWinDll.dll

Successfully registered DLL MwtWinDll.dll

[If I tried to copy the dll to the wine structure first and register that copy I got:

DllRegisterServer not implemented in DLL C:\windows\system\MwtWinDll.dll]

If it seems weird to install wine-mono and then remove it as is done above, it's to get around a bug which causes dotnet20 installation to fail/

Anyway, you're pretty much done:
 wine ~/.wine/drive_c/Program\ Files/Molecular\ Weight\ Calculator/mwtwin.exe

Yay!

Comment:
Getting there was a bit of a trek, passing though a whole lot of different sets of dlls:
winetricks msflxgrd

winetricks vcrun2005
winetricks vb6run
winetricks mdac28
winetricks comctl32ocx

winetricks comctl32

The solution above should suffice though.

I even ended up installing mol weight calc on a windows box and using dependency walker, but not even that sorted it out -- googling for scrrun did it in the end.

In particular this last error was bloody annoying:

"Object doesn't support this action." What, saving?

"Error saving default options file. Use the /X switch at the command line to prevent this error."

But it was solved by doing winetricks wsh57
