Installer Failed to Initialize. Download Adobe Support Advisor - Advisor says no issues

You will want to review your PDApp.log file to discover what is causing your difficulties.  The following steps can be utilized to allow you to discover your error message:

1.  Navigate to the PDapp.log file in one of the following folders:

Note: The following folders are hidden by default. If necessary, use Folder Options (Windows) or Terminal (Mac OS) to show hidden files.

• Windows Vista and Windows 7: \Users\[username]\AppData\Local\Temp

2.  Open PDapp.log in a text editor such as WordPad (Windows)

PDapp.log records installation attempts sequentially. Each line in the log starts with a date and time stamp, which indicates when the installation was attempted. Each attempt starts with a Build Version number.

3.  Analyze only the most recent attempt. If you can’t determine which build attempt is the most recent, delete PDapp.log and run the installer again.

In the most recent installation attempt, look for lines identified by [ERROR] or [FATAL]. For example:

5/1/2010 13:49:48.847 [ERROR] DWA.SystemRequirement SystemRequirements check FAILED for payload - Adobe Media Encoder CS5 PCI WRAPPER

5/1/2010 13:49:20 [FATAL] PIM - Error could not create PIM Common Folder Path... F:\Program Files (x86)\Common Files\Adobe\OOBE\PDApp\

4. Search the Adobe knowledgebase for a TechNote that provides a solution to each error message. Omit paths and machine-specific information from search strings. For the preceding errors, for example, you would search on “DWA.SystemRequirement SystemRequirements check FAILED for payload” and “PIM - Error could not create PIM Common Folder Path.”
