There[SQ]s no official "Adobe Special Collection for Windows 7". Adobe doesn[SQ]t release product bundles specifically named that way. It[SQ]s possible you[SQ]re encountering :

*

A reseller[SQ]s custom bundle:

Some resellers might create their own packages of Adobe products and label them creatively. This wouldn[SQ]t be an official Adobe offering.
*

Misremembered or inaccurate name:

The actual name of the product might be slightly different.
*

A pirated or counterfeit collection:

Be extremely cautious if you encountered this offer outside of official Adobe channels. Pirated software is illegal and carries significant risks of malware and instability.

To find legitimate Adobe products for Windows 7 (note that support for Windows 7 has ended, so software compatibility isn[SQ]t guaranteed), you should visit the official Adobe website directly. Look for individual Creative Cloud subscriptions or individual software purchases that might still function on that older OS. However, expect limited or no support and potential compatibility issues.
