Hi Kiran,
as IP1 is not installed on top of 9.24, it might not be required, however it's always recommended to apply the latest available IP patch (in this case 9.24 IP1) PRIOR to the update to a higher version, due to potential important fixes which have been incorporated into the IP.
> Also , can i directly install 9.24 without installing 9.20 , will it work??
No, as mentioned before. You have to install 9.20 first, then update to 9.24.
9.26 is an excpetion, this is a full installation.
> Please share me the link to download 9.20 for windows 64 bit.
You can download the software from SSO
SSO -> Product Information -> Downloads -> new Pop up with MyUpdates
..
You can now access software entitlements in the new Hewlett Packard Enterprise Software Licenses and Downloads Portal.
You will need the original Order Number (not the SAID) to access the entitlements in this Portal.
NOTE: Although license entitlements are now only available in the new portal, My Software Updates will still be available for software downloads
..
and proceed from there.
You also can use the Eavluation web site which allows you to download BSM with a trial license for 60 days
