SIDX 6 runs only with IGOR Pro 7 32-bit, not with IGOR Pro 7 64-bit.

Install SIDX 6 using the installer. If the installer gives a warning that it cannot find IGOR Pro, follow the next instructions. If the installer completes without a warning, follow the instructions further below.

Instructions when the installer gives a warning that it cannot find IGOR Pro

In the SIDX 6 installer, choose the installation folder:

'C:\Program Files\WaveMetrics\Igor Pro 7 Folder'

The SIDX 6 installer will (incorrectly) place the SIDXXOP.xop file in the folder (notice the difference between 'Program Files (x86)' and 'Program Files'):

'C:\Program Files (x86)\WaveMetrics\Igor Pro 7 Folder\Igor Extensions'

Move the SIDX 6 files to:

'C:\Program Files\WaveMetrics\Igor Pro 7 Folder\Igor Extensions'

The SIDX 6 XOP files are named SIDXXOP.xop.

Instructions when the installer completes successfully with no warning

If the installer completes with no warning, the installer has placed the SIDX 6 file with an earlier version of IGOR Pro installed on your computer. You will have to copy the files to IGOR Pro 7. The SIDX 6 installer placed the files in:

'C:\Program Files (x86)\WaveMetrics\Igor Pro Folder\Igor Extensions'

Copy the SIDX 6 XOP file to:

'C:\Program Files\WaveMetrics\Igor Pro 7 Folder\Igor Extensions'

The SIDX 6 XOP files are named SIDXXOP.xop.

After you have copied or moved the files, IGOR Pro 7 32-bit should be able to find the SIDX 6 XOP properly.
