after installing, a message appeared that software successfully activated but actually I am not able to locate it in my PC no shortcut for it neither does not exist in program files as if I am not install it in the first place.
I did repeat the installation process few times but with no success, same result no trace for it in my PC

Windows 7 Pro 32-bit.
A note on cleaning up after install:
After installing and closing the program, at first I could not delete Setup.exe and Setup.gcd, a persistent small empty screen kept appearing on my desktop, and, while the program on the taskbar showed itself as running, I could not find it in Task Manager.
After a cold reboot the problem appeared to be solved -- I could delete the two Setup files, and the other indications of the program running had disappeared.

Hmm...this thing can't even recover items deleted from the recycle bin? I had a high school coding project that could do that. Should be a fundamental capability for any un-eraser.

Installed ok after disabling antivirus and did the registration but now it says "Days to registration: 180 days" Is that normal? Please advise...

With a product name as specifically enticing as today's, I'm surprised the developer has gone for a domestic home-user audience instead of security and law enforcement agencies.

Forensic recovery of over-written HDD data blocks is a time-consuming and expensive business; electron microscopes ain't cheap. At $18.63 retail, this uneraser of erased data is an astonishing bargain. Even at $1,863 retail it would be sought by all the above-mentioned. Actually: $18,630 would still suit the FBI's budget just fine.

I'm almost tempted to DL and try to unerase that which has been erased from my hard drive. Almost tempted to find, in the wealth of verbiage penned by this developer, a single solitary example of an erased file or folder being recovered by Uneraser 3.9. It's tempting, too, to check out the version history of Uneraser from 1.0 to the present because a product's evolution says everything about its progressive refinement.

Instead though, because I'm short of time, I'll leave the developer to come on here and tell me how $18sworth of software can feasibly attempt what even $100,000sworth of electron deep-scan forensic hardware has no guarantee of achieving.

Meantime, if need arises today for me to recover an inadvertently deleted file or folder from my hard drive, I'll use Piriform's always-free Recuva. It doesn't promise to un-erase anything, but at least seems to manage things rather better than Uneraser 3.9:

"Unfortunately, this program isn't capable of recovering the files you lost after the storage device was damaged or infected, the disk was formatted, or the Recycle Bin's items were deleted." (Ashley Griggs, Software Informer):

Though I take my hat off to Hetman for linking from its own website's "Expert Reviews: Reputed computer publications and data recovery laboratories recommend using our software. See the independent experts' opinion" to a, er, recommendation which demolishes its own product, I'm not going to be able to un-erase from my mind the notion that this software isn't ever going to do what it says on the tin -- and that if it can't even live up to its own self-description, then no 6-month trial is going to alter that.

Thanks, GOTD, and Hetman. But no thanks.

Got ''Installer Integrity Check Failed'' message - never seen that before. Any fix? Also downloaded it from their website but doesn't register with the GOTD key.
