Various installer bugs

[t-b]

During MIES installation, Miki is finding:

1)  When installing MIES, the installer places AxonTelegraph64.xop in C:\Program Files\MIES\XOPs-IP9-64bit, which references Igor Pro 9, even when that version is not installed.
 Would it be possible for the installer to detect the currently installed Igor Pro version and reference the appropriate directory?

2. When uninstalling MIES, some* Igor-related files that reference the MIES installation directory are not removed. It would be helpful if the uninstaller could remove all related files and references automatically.

*C:\Program Files\WaveMetrics\Igor Pro 10 Folder\Igor Procedures\MIES_Include
 C:\Program Files\WaveMetrics\Igor Pro 10 Folder\Igor Extensions(64-bit)
