can't locate kronatools.pm

[vappiah]

Hi Developers,

I installed Kronatools as root on a system so that different users can use it. I tried running ktImportTaxonomy using a regular user account and I got this error message

Can't locate KronaTools.pm /opt/apps/kronatools/KronaTools-2.8.1/scripts/../lib/KronaTools.pm: Permission denied at /opt/apps/kronatools/KronaTools-2.8.1/bin/ktImportTaxonomy line 17 Begin failed--compilation aborted at /opt/apps/kronatools/KronaTools-2.8.1/bin/ktImportTaxonomy line 17

I tried setting execution permissions but the error message still persists. Please advice
