I have added an Installer class and within the class i'm overriding Install method. Within this method i want to get the path where MSI is being installed? (Directory user have chosen to install the application) ?

I tried the following and it gives me empty string,

string s = Context.Parameters["SrcDir"];

I finally found how to get the target directory path from installer class

string installationPath = this.Context.Parameters["assemblypath"];

How do we get the current MSi path?
@Ranish What do you mean by current MSI path ?
Would be interesting if this can be set from the installer-class.

I have iterated over all the available parameters to my installer class and found it only has:

Param: logfile, Value: 
Param: lo, Value: 1           // custom parameter set in custom install action
Param: action, Value: install
Param: installtype, Value: notransaction
Param: assemblypath, Value: D:\InstallerTrialHelper.dll

From it, I see we can use assemblypath directory to know which install directory is selected by user.
