MSG Previewer is an outlook message (.msg) preview pane for 64 bits Windows.
Microsoft doesn't support the a 64 bit previewer for .msg extension in windows explorer. These dll files will make it work.
Installation instruction
Download installerYou can put them anywhere you like, preferable a path you can type easily. In below example i've put them under d:\MSGPreviewer
You also need .NET 4.5 , a newer version is good too.
Now you need to run Command line in administrator mode. You can do this by create a shortcut to cmd.exe and right mouse click and choose run as administrator.
Goto the directory: C:\Windows\Microsoft.NET\Framework64\v4.0.30319 , by typing: cd C:\Windows\Microsoft.NET\Framework64\v4.0.30319
then type these two commands:
regasm /tlb C:\MSGPreviewer64\SharpShell.dll
regasm /codebase C:\MSGPreviewer64\msgpreview.dll
This will register the dll files as com object and the previewer should work now.
Windows 10 version notes
If the normal version doesn't work, there is a fallback to the windows 10 version of msgpreviewer. This version shows the text as plain text.How to change the font size
the newest version reads a registry key from: HKLM\software\brandsict\msgpreviewer\fontsizeThe value of fontsize determines the size used
In the zip file there is a .reg file you can run to create the registry key.
Errors
This is not a valid .net assembly
