I had a HD failure (MAC) losing all my applications. Tried re-installing using original disk S-SW55 that came with K10D and does not work. The Pentax Installer Icon appears but double-click will not open the Installer Screen. Down loaded latest version but will not install because does not find a previous version on my computer. Pentax USA Web site is having problems so NO help there at the moment. Just wondering if anyone else has had problems with this CD-ROM.
The disc that came with the K10D had a bug in the Mac installer. The fix is to right click (ctrl+click) on the installer and select "show package contents". Then navigate to the specific installer for your language as I recall (it's been a while since I have done this). The specific installers should work.
You have a better memory than me. I don't remember how I installed it 2 years ago.
Now I will update to the latest version. Again, thanks for helping me.
