Activating

If you have a CS4 program per @Shivangi_Gupta you will not be able to activate it

The CS2-CS3-CS4 activation servers have been removed from service
-https://helpx.adobe.com/creative-suite.html?promoid=19SCDRQK
-So even if you have a disc or saved download, CS2-CS3-CS4 are completely dead
-Adobe also no longer supplies the special non-activation version of CS2-CS3-CS4

Hi @Invizij Architects Inc.,

We appreciate you contacting us. As per your accout info, you do not have any  any active subscription associated with your email address however there is a active perpetual license for Adobe InDesign CS4.

We believe that is what you're looking for.

Regards,

Shivangi 

1. you can install the latest and 1 version prior versions using the cc desktop app. you must have a subscription because previous versions are not available with trials. other versions are revealed after clicking file preferences>apps>tick show older apps (at panel bottom).

2. for versions cc 2019 and older, use prodesigntools.com*.

3. for versions newer than cc 2019 but older than one previous version, contact adobe support for links**.

---------------------------------------------------------------
* most (but not all) adobe download links are available from prodesigntools.com. https://prodesigntools.com/adobe-direct-download-links.html

follow the directions (esp, step 1)

save the install file. it may not remain online.

thank jim @ prodesigntools.com

** this support is currently not available. ie, there's a significant gap (between 2019 and last year) in the available previous versions.

opposition to this decision (to limit available previous versions) has been conveyed to adobe officials who are therefore aware of the problems caused by this policy. however, unless/until changes are made, nothing can be done to legally access these files.

The forum questions are answered by users like you. We can't answer account-related questions in the InDesign forum. You need to contact Adobe for help:
