I was just doing a clean install of PhotoPost Pro 5.02 and modified config.inc.php with the internal path on a IIS server with the following:
$PP_PATH = "E:\InetPub\tobeme\sites\domain\photos";

When completing the final step in install.php, it complained stating it could not find my datadir and it was not writeable. It listed the path as:
"E:\InetPub obeme\sites\domain\photos\data"
** Note how there is now a space after "InetPub"

(there was a forward slash in the path that was outputted as the error, just cannot recall if it was before "data" or after it. Not sure if this will cause a problem later)

Anyhoo, it was assuming "\t" was a tab. I had to enter the path as"
$PP_PATH = "E:\InetPub\\tobeme\sites\domain\photos";
This resolved the problem.

Now I am running into the problem with adm-index.php, it is giving me warnings:
"Warning: opendir(E:InetPub obemesitesdomainphotos/data/) [function.opendir]: failed to open dir: Invalid argument in E:\InetPub\tobeme\sites\domain\photosadm-main.php on line 19

Warning: readdir(): supplied argument is not a valid Directory resource in E:\InetPub\tobeme\sites\domain\photosadm-main.php on line 21

Warning: closedir(): supplied argument is not a valid Directory resource in E:\InetPub\tobeme\sites\domain\photosadm-main.php on line 29

Best Wishes,
