Re-installing Rights

[Thulemanden]

Can the downloaded copy be stored an re-installed later or will re-installation require a new purchase?

Does it absolutely have to be installed on the same PC, or can it be moved to anoter PC?

Holy Cow .. I know this person from a Danish IT-Forum about 4 years back …. 😀

There are two questions here I think:

1) Your legal rights

2) Your practical/technical possibilities.

1) License terms (for PRO and ENTERPRISE) simply state that you have the right to install to one computer for each License purchased and have free upgrades and support for a year. After that year you must pay for an new license (PRO) or an upgrade (ENTERPRISE) if you still want to be able to upgrade. But you can of course continue using an old version as long as you like without purchasing an upgrade. If you need to move it nothing forbids that.

2) The technical possibilities and limitation follow the common shareware concept of a KEYGEN mechanism. To make the program work you must enter a USER and a REGISTRATION CODE. To be functional those must 'match'. The 'match' is verifed with various sorts of hashing, encryption and similar algoritms. Such mechanism can be pretty weak (SQLyog 3 and 4 was pretty weak!) or pretty strong (5 is) and they can be more or less difficult to recover from bit patterns on the hard disk where things have been permanently or tempoarily stored. BUT there is NO WAY with such system to prevent a repetition of the registration proces (no matter how strong the algoritms are) on another computer. Computer B can by no means know if computer A has done the same thing two weeks ago. So …

1) yes: I you want to move to another computer, you can easily do so. Comuter B does not know what Computer A has been doing lately. How should it? You don't even need to be connected when registering!

2) and: The binary installer linked to in your confirmation mail and the registration details there will always be usable together – at least on all type of Windows systems (including WINE) that we know today. There is no 'expiry' built in (there may be in BETAS and RC's as we don't want people to use them forever !!!) .

and this you did not ask:

3) we don't use ACTIVATION either. (that is linking the validity of the license to a specific hardware configuration where it was first registered). With a low-priced product like SQLyog ACTIVATION (like Microsoft, Adobe etc. do) is out of question – those activation server systems are simply too expensive to access. And involves a lot of monkey work in helping people out when they change hardware – maybe simply because it is broken and they need to. This does does mean that some hardware information cannot be used with the KEYGEN (using the serial of the harddisk where it is installed as part of the 'seed' for a random generator generating an encryption key could be done for instance). But still that will not prevent install on other systems.

4) And actually .. when uninstalling SQLyog the registration information is not removed from the system. So once you install again on that computer it won't ask for details next time. Unless those 'information bits' (whatever it is 🙂 ) have been deleted/overwirtten (by reformatting, by restoring (parts of) a backup from before SQLyog was installed etc). This can actually be a little problems in special situations. If you purchase a second-hand computer with Windows installed and where SQLyog has been installed before (but not there anymore), you will not be able to enter your registration details as there are allready the registration details of a previous user. An issue for us to consider, I think. Also we have had quite a few situations where some person has (thoughtlessly) registered to himself when purchasing and not to his company/employer!

We belive that SQLyog is an attractive 'found' for its price. Of course some may 'borrow' a copy of some registration details. Every engineering student can crack a 3000$ autoCAD in 5 minutes (I think I remember something about that … ). .. and undoubtedly SQLyog can be too. But in our county a personal copy of SQLyog Enterprise costs the same or less than a theatre ticket or 100 cigarettes .. is it worth it?

This is a good text for FAQ.

[peterlaursen]

I can easily find a place to add it!

But don't you think we should provide an option to remove/updated outdated registration information from the system?

I can think of two ways to do so:

1) Provide a small .exe that does this as an additonal download available

2) A 'change registration' option from help menu.

[Ritesh]

Yup.

Thats a good idea. Added for v5.2. A small GUI application should do the job.

Hello peterlaursen,

I want to use my new registration without reinstalling Windows XP. How to un-register previous install?

Thanx in advance 🙂

[peterlaursen]

If I understand you correctly this is not possible.

why a 'new registration' if you had one before?
