如何安装SAS里面的IML，我的IML怎么不能用呢？
我安装的SAS 9.2,然后运行 proc iml显示如下错误。
ERROR: The SAS/IML product with which IML is associated is either not licensed for your system or the
       product license has expired. Please contact your SAS installation representative.
1    proc iml;*invokes IML;
ERROR: Bad product ID for procedure IML.
2    a = 2; *scalar;
3    b = {1 2 3 4}; *1 x 4 row vector;
4    c = {1.0 0 0, 0.2 1.0 0, 0.8 0.4 1.0}; *3 x 3 (correlation) matrix;
5    quit;

然后我去安装了IML studio 3.4,然后打开出现如下错误

拜托大家帮忙看一下吧。悬赏20.
