i do have an IPS-4240 running in my network.it was running using IPS Version 7.0(2) E3.
As long as we cannot take any signature update before upgrading our sensor to Engine E4, i was obliged to go on and upgrade the IPS.
One problem occured with ASDM. the ASDM-IDM running was version 7.0 [V1.5(37)].
Using the same ASDM i cannot acces the Sensor, it do always ask for upgrade. even while pressing "upgrade now" several times the upgrade shows as successfull but in real life it do not success. it do still run under the same version.
i can access the IPS through https, then run ADM, it do works and it do appears version V1.5(49). If i do try to save the dm-launcher at my HD and then run the setup it do not works.
sum up, each time i have to access the IPS through ASDm, i have to use the HTTPS first then the "run ADM" from the site opened second.
