How do I specify a directory for the MSI install that has a space in it?

[Angel Velasquez]

Hello,

I need to set up a silent install config for SourceTree Enterprise and I'm currently attempting to use this as my install command:

msiexec.exe /i SourcetreeEnterpriseSetup_3.4.18.msi ACCEPTEULA=1 INSTALLDIR="C:\Program Files\SourceTree" /quiet

This didn't work but I found out that it will work if I remove the space in "Program Files" I thought having the directory path in a string would make it treat it as a string instead of a literal. My command gets treated as

msiexec.exe /i SourcetreeEnterpriseSetup_3.4.18.msi ACCEPTEULA=1 INSTALLDIR=C:\Program Files\SourceTree /quiet

Where Files\SourceTree is treated as a MSI flag and crashes the install. How can I include a space for the silent install within the INSTALLDIR flag? I double checked and it does work when I do not have a space but I have to install it to Program Files given the circumstances.

The escape character in PowerShell is the grave-accent(`), so try this:

msiexec.exe /i SourcetreeEnterpriseSetup_3.4.18.msi ACCEPTEULA=1 INSTALLDIR=`"C:\Program Files\SourceTree`" /quiet
