Inklingo #1, #2, and # 3 will open with Windows 7.
However, Inklingo # 1 and # 2 CDs will NOT open with Adobe Reader X. Inklingo #1 and # 2 must be opened with the version of Adobe Reader included onthe CDs, and Adobe Reader 6 has compatibility issues with Windows 7.
All you have to do is click OK in the compatibility boxes (ignore their warnings). I don't know of anyone who has not been able to open # 1 and # 2 CDs so far, but eventually the CDs will be obsolete. Those collections are being replaced with several downloads.
NOTE Please be sure to close Adobe Reader BEFORE you insert the CD. The # 1 and # 2 files are enormous, so they may take a minute or two to launch and load the password. (Even I do not know the passwords on the CDs.)
Inklingo # 3 See the detailed illustrations in the System Requirements for opening with Windows 7 and Windows 8.
