I believe a lot of people have encountered the same problem as me: php5.3 above version no longer support Zend Optimizer, but shopex such sites must be a high version of the Zend to use.
After the n hours of grief-seeking, and finally finished, but ultimately can only to Shopex succumbed to ...
First, if you want to use Zend Guard Loader, the php5.3.x version must download the NTS version, and it must be VC9 compiled. These two points must be noted that there is a wrong can not use Zend Guard Loader.
At present, Wampserver 2.1e (32-bit version) of the php5.3.5 is VC6 compiled, so wampserver 2.1e environment is not directly Zend Guard. Wampserver 2.1d (64-bit version) of the php5.3.4 is VC9 compiled, but it is the TS version, so it can not be used.
If you want to use the new version of the Php+zend guard, you can only go to the PHP Web site to download a NTS version of the VC9 compiled PHP.
However, even if you use the new version of PHP and Zend Guard, also can not use shopex4.8.5, because Zend version problem parsing error.
Therefore, in order to use this version of the Shopex, can only be forced to switch to PHP 5.2.x version +zend Optimizer 3.3.3.
Of course, here also to note that the PHP 5.2.17 must be a TS version of the VC6 compiled talent and Zend Optimizer 3.3.3 with, really his mother of Metamorphosis!
Finally, the environment can be installed after the Shopex. However, when you install it, you will never go through the process of creating a new database.
View the MySQL database found only 97 tables, and fully installed should be 109 tables. Checked a lot of places, also do not know where the problem.
Finally found the reason, is the MySQL version is too high caused. Then from MySQL 5.5.8 back to MySQL 5.1.55 is normal.
