[WiX-users] Unable to add files in C:\Program Files (x86)\MyApp

[Kshama Bafna (Persistent Systems Private Ltd)]

Hi,

I have created an MSI using WIX and the installation is done correctly by the MSI. When I install my application to D:\MyApp, the application works fine and as expected it writes a few files in the same location. However, when I install the application at C:\Program Files (x86)\MyApp location, the application is unable to write the files in the installed location and it throws an exception 'Access Denied'. I do not get this exception when I run the application as 'Run as Administrator'.

Please let me know how can I get rid of this exception. Are there any permissions which could be set in the WIX file for the folder?

Thanks in advance,
Kshama

It's because the folder is read-only unless you have full admin rights. You can have the installer
make it writable like this:
<Directory Id="examples" Name="examples">
<Component Id="examples_permissions" Guid="GUID_GOES_HERE">
<CreateFolder>
<Permission GenericAll="yes" Read="yes" ReadAttributes="yes" CreateChild="yes" Delete="yes"
DeleteChild="yes" WriteAttributes="yes" User="Everyone" />
</CreateFolder>
</Component>
</Directory>

This type of thing is common when moving to a UAC system. I suspect your OS version uses UAC, so:

1. I would recommend you look at user profile data folders for this kind of data storage.

2. Maybe your app has always required admin privileges but now you're on a UAC system, so maybe you need an elevation manifest?
