Is it possible to use the program without giving 'auto renewal' confirmation? If so, I would like to use it and if it is really good I would buy It after its expiry period (1 year).

is there a product key needed to activate?

The download went fine, but the installation failed because Net Framework 4.5 is required. My ancient rig runs XP and so does not support NF 4.5, but in the System Requirements it is stated explicitly that the program runs on all versions of Windows including XP.
Moreover, to activate the program it is necessary to give name, email and telephone number: I did so, but the promised email has not materialised (yes, I did check my spam folder!). I thought I saw an error message flash by, but then I was asked to check my messages and all seemed well.
Maybe it's for the best, as the program needs 500MB of space, oddly as the file downloaded is only 11MB!

... the minimum of the space for installing computer optimizer is 500 MB . It looks like you can't use that program if you have a PC/laptop with an SSD of 125, 250 or 500 MB, let alone an SSD of 1GB, half of which you can be considered as lost, because computer-Optimizer will be on it.
The reason I cannot use the program is; Because this Windows 10 PC has a print-SSD of 125 MB, the Windows 8.1 an SSD with SATA connection with a size of 250 MB.

post installation, it doesn't open even tried opening it as an administrator. Using Windows 11. Anyone else facing this issue?
